is this is the ZDK-03 ?

[Argus Panoptes]

i think the rear left wing is not showing is normal because its higher than the wings and also much smaller you can notice it on the other jet next to it the rear left wing is barely showing . about the disc no comment

If you look at the shadow of the right rear wing and its length, then the edge of the left rear wing should be visible on the left side of the fuselage. And where is the shadow of the disc itself? And what is causing the streak artifacts along the shadow of the main wing?

Digital artifacts are the likely answer.
