The purpleish color is gone in ady's CC version.

The tie fighter shots you mention really solve the angle/curvature problem or can be used as reference..

but in the cockpit shots the curvature of the superstructure gives us teh impression that there are two camera lenses at the same time with weird effects.. and yes camera lens distortion is an other thing from the tilt ;)

The only clue i have from the fallen piece is luke's blaster?

And yes like i said my model based on the wrong blueprints :)
