Your dad is French, go to Renault. Then you can apply for a visa designing the new Ladas. If they looked like that I might buy one.

Add a large number of pylons and weapon points like conformal positions for R-77s and R-73s plus room for external fuel tanks and heavier air to ground weapons and keep the price to around 20-25 million each and I would think you would have an excellent light fighter for export and for gap filling.

The armament layout is similar as Indian MiG-21 "Bison".. as well as
RADAR's, the Kopyo.. however i think fitting Pharaon-M would be much
better options.

Horizontal tail surfaces and canards and vertical tail surfaces... too much.
It looks like an Su-27UB that stopped suddenly in the side view.
I must say as per your requirement of a light attack plane with high subsonic flight the plane must be highly agile ~~manoeuvrable this only can be provided by cluttered control surfaces [besides this is the legacy of Russian designers]. For light attack planes one not need any heavy payloads strictly speaking light aircrafts requirement must be met with at most three underwing hardpoints each.
I guess in the weight range basically a composite Yak-130 with a single late model RD-33 engine, a single seat and a larger wing with high subsonic flight performance would do the trick as long as you fitted it with a decent little radar set.
Cluttered? We are not designing any webpage Garry

Now here is a problem... four wing pylons and that big flat empty belly area with nothing on it?
The standard launch rail for the R-77 has an arm based catapult, so there are few problems with separation even from an internal launch bay let alone a pylon or conformal body launch position.
If I was arming this aircraft I would keep the four wing pylons for fuel tanks and air to ground weapons and I would put short range AAMs like R-73 on the wingtips and put 6... yes 6 conformal BVR missile points on the body in two rows of three.
The R-77 was designed for internal carriage and in that role its rear grid fins are designed to fold forward for carriage and flip out on launch. Conformal belly positions with the grid fins folded would maximise the air to air capability of this aircraft while freeing up wing points for other purposes... which in the air to air role could be more AAMs, jammer pods, or for the air patrol mission fuel tanks to extend range. For the air to ground role it could carry up to 500kg laser or sat guided bombs and fuel.
An extra centreline position could be used for a large fuel tank as well and a wing root mounted 30mm cannon would round out the armament.
Here is a very rough image of the belly mounted missiles... note I simply removed the rear grid control surfaces but in practice they would actually be folded forward and would deploy on launch... this is what they were designed to do for internal carriage.
In addition to these belly mounted weapons I would add wing tip positions either for R-73s or wing tip ESM pods.
Good idea.. however since the fighter itself is small (13 m) i don't
think she can go up with numerous armaments , and still retaining
required maneuvering capability as Interceptor, heavy armaments will
also increase empty weight which in turn will affect the cost ..not
really something i want for a "people's fighter" like mine
for typical Cruise missile however , Her RADAR will not be sufficient,
since it's optimized to fight aircrafts and bombers , she will need to
be accompanied by AEW or Interceptors with larger RADARS .
Your upgrades may need larger fighter to accommodate her armaments
One thing I observe is why this plane has angled air-intakes?
As you can see above the angled air intake in bomber edition are fitted
quiet aft the fuselage because air reaching at that point already had
loss great deal of kinetic energy. Also its a bomber [with a speed of
not more than .6M] & not any jet fighter plane.
**F-16/F-35,J-10/JF-17 all are fitted with DSI intakes for this very reason
What a shame you picked that bomber as an example because that bomber... the Tu-160 can fly at mach 2.2 and as such is actually faster than either the F-16 or F-35.

I appreciate what you are saying, but I am talking about AAMs, which in general are the lightest ordinance most aircraft carry routinely.
6 Belly mounted R-77s would weigh 175kgs x 6 which is just over 1 ton so the performance penalty will be minimal... especially because of the low drag configuration, the missiles themselves are only 3.6m long with a body diameter of 20cm and a wing span of 70cm, but that is the gridded fins extended.
Equally with AGAT making new smaller ARH seekers it is all together possible to have R-73s with ARH seekers fitted for a mini R-77.
If 6 is too ambitious then two rows of two for four belly mounted missiles should be easier and would still leave 2 wing pylons and a wing tip position.
The point I am trying to make is that just because it is a light fighter, don't limit its flexibility by skimping on the weapon options. A light fighter that has 4 R-77s and 2 R-73s with 4 wing pylons free for external fuel tanks, jamming pods, satellite guided bombs of modest size, or TV or laser guided weapons is much more flexible than a warmed over Mig-21 with 5 pylons in total, which means 4 AAMs and a fuel tank or 4 bombs and a fuel tank for medium range missions and the same payload minus the fuel tank for short range missions.
To be truely multirole you need the capacity to carry things you will need for a variety of roles. With wing tip pylons you can either carry short range AAMs or jammer pods, and both would be rather useful depending upon your opponent. This means in a real war it can have wing tip jammer pods and wing mounted AAMs and fuel tanks to extend range and fight persistence. In a COIN conflict you can drop the jammers because the enemy wont have radar or radar guided weapons and carry extra AAMs if they have limited air power like Georgia or nothing. For COIN fighting you could put a Damocles pod on one wingtip and and some sort of towed decoy system or flare dispensor thing on the other to balance it. This will give the pod an excellent view and leave four wing pylons for guided weapons or even marking weapons... or unguided rocket pods with rockets fitted with the Ugroza guided weapon package using the Damocles pod to find targets and pass data to HQ while for smaller targets like a convoy of trucks a single pod of 20 x 80mm rockets with HE frag warheads and laser guidance should deal with the problem. Four 20 round pods gives combat persistance and two 20 shot 80mm pods and two 5 shot 122mm rocket pods gives flexibility for harder targets where the 122mm rockets with 30-50kg warheads including concrete piercing should do the job.
IRST or targeting pod like Damocles should allow it to find cruise missile targets easily enough... especially when vectored to the target location with an integrated airdefence/space network...
The purpose of my suggestions is not to make some mini super fighter like some 5 year old who puts missiles on the wingtips and the tips of the horizontal tail surfaces and the tips of the canards as well.
The purpose is that most of the time this aircraft will operate with 4-6 AAMs... conformally positioned on the belly of the aircraft and the wing tips and that the wing pylons remain empty to reduce drag.
For longer patrols external fuel tanks will be carried, and for ground targets the wings will carry the air to ground ordinance while remaining armed for the swing role to cover other aircraft after the air to ground weapons are delivered.
Max payload will not be anything like the F-16 at 7 tons, and normal load will be 1-2 tons and for longer missions will be in the 3-4 ton range at most with most of the extra weight being fuel in external fuel tanks.
For air to ground missions with 4 AAMs say 700kgs, two 500kg guided bombs or missiles (like the new Kh-38 series missiles) and two 1,000 litre fuel tanks... about 4 tons tops.
I understand , well however the fighter might be placed in the "second
line" to stop any leakers passed through larger Interceptors .
Targeting pod may help, however i'm still doubt that it will work in any weather situation.
And i'm don't really think that Conformal weapon bay would offer
clearance and capacity as conventional pylons, mechanisms required to
open the bay and to "hoist up" the missile should take into account too,
more missile inside the bay would means more mechanisms is required ,
thus the bay size would scale up accordingly .. and weight and wetted
area increase are inevitable .
