Rendering of FGFA:
fgfa_by_parijatgaur-d4963jk.jpg

This pic is by far the best 3d version but actually it has some serious limitations. The nozzle shown in the pic is 2-D while PakFa/FGFA have 3d nozzle.

Those extra small wings near cockpit like J20 is not the part of actual Pakfa and the cockpit is a big higher.

Actually the "small wings" are not canards like on J-20, EFT and Rafele but are LEVCONS (leading edge vortex controllers) similar to those on N-LCA (and will be present on PAK-FA/FGFA). The LEVCONs are control surfaces that extend from the wing-root leading edge and thus afford better low-speed handling for the LCA, which would otherwise be slightly hampered due to the increased drag that results from its delta-wing design. As an added benefit, the LEVCONs will also increase controllability at high angles of attack (AoA). These are far better for stealth a/c than large canrds that increase RCS.

PAK-FA with LEVCONs clearly visible:
