A very nice spoof....or a CL ad for Photoshop.
The first obvious giveaway, is the lighting, as others have noted. The shadow on the bottom of the wing and stab indicated that the light source was perpendicular to the long axis of the plane. In this case, the light source would have to be right on the horizon, and, there would have to be a similar, very long shadow to the side of the pilot, which there isn't.
Correct me if I'm wrong, but the only three times that a plane is vertically down, close to the ground, is in the reverse wingover, the outside square loops, and in the outside portions of the square horizontal eight.
If the pilot were in a reverse wing over, his body would be rotated 90 degrees from the plane, and we would see his left size.
If the pilot were flying outside square loops, the plane would be to his left of center.
If the pilot were in the outside portion of the square eight, he would be flying an angle 45 degrees to the left of his center.
It was fun, anyway. What else have you got?? We need something harder !!
Cheers.
