Did you notice neck is already broken when the AT-AT falls?

When we see it fall, the neck is parallel to the ground (so it can break in the desired way and not dig into the snow like a spear), which we can assume is a manouver the AT-AT drivers did to avoid dying in the crash (lifting the "cockpit"). But you can clearly see that where the neck connects to the body, the lower section is already torn apart. Nothing difficult to be fixed with some editing, I guess.

And for the running troopers... Maybe could work if they were more than just two of them? Or simply remove the running troopers and the Chief Trooper yelling? :)
