Well, your details are unfortunately wrong.
The engines I referred to were the OMS engines, which correspond to those two black areas on the upper white bulges. They're exactly where OMS engines should be.
I agree that the whole thing looks wider than it should -- and this may well be an optical illusion, or perhaps an artifact of how video is shot. And the wingtips may also be gone, which would exaggerate the width.
The fact remains, however, that there are recognizable Shuttle parts, and they are exactly where they ought to be, and the view looks right from the angle at which it would have been shot.
Your "optical illusion" must have somehow included symmetric OMS engines, a body flap, a nose, and a very close approximation of the proper delta-wing shape, and the smooth curvature of the wing leading edge toward the nose.
That's one amazing optical illusion!! It's far easier to accept that this is a real image of a real Shuttle.
