Understandable about the foot resizing. A couple of other suggestions: would it be possible to have the foot crush into the snowspeeder more? Also, during the shots of the snowspeeder flying around the AT-AT feet (where the camera tracks the snowspeeder), would it be possible to create a background behind the snowspeeder to reflect that the camera is spinning around the AT-AT (and we would see more than blank sky)?

But if someone was to prove that this thing can look 100% realistic with Cg then i'm willing to change my mind

I concur; this could be a good project for someone who is really good at CG manipulation.

I also like Angel's idea of adding snow impact FX around the AT-AT feet during movement.
