One more thing about the AT-AT foot:

I understand that the ambient light from the surrounding snow may counter this, but would the foot cast a shadow over Luke (in his reaction shot) as well as directly over the snowspeeder before crushing it?

Regardless, keep up the fantastic work, Jaitea! Hopefully Ady will accept and include it into the edit. Even as your mock-up stands as it is, it works perfectly and I never noticed anything that would even indicate anything was manipulated.

In fact, when I first clicked on your link and watched it, I was wondering: "okay, so what was changed?" Then I went back to the forum and took a closer look at the original footfall shot and realized how much bigger the AT-AT foot was in your mock-up.

One last thing: I love your alternate sound effects as well. I can't say I hated the whining hydraulic sound FX, but it didn't seem right. In fact, shouldn't the AT-AT feet be making louder, bass-ier sounds similar or identical to the sounds they make when the rebels first see (and hear) the AT-ATs? In fact, do the AT-ATs make any noise after the rebel with the binoculars sees them for the first time?
