Yup... don't forget the fantastic scale work Savmagoett has already done:

rescaling the foot on a still image is one thing, but actually doing it on a moving image is completely different. I know, i've tried. The main problem is that part of Lukes body covers the foot as it crushes the snowspeeder. Scale that foot up and you have a huge section of lukes body. It isn't so easy to cover that up, especially when the foot flipper is moving. The only way to do it would be to create a new CG foot or build a new foot and speeder miniature.
