I like it, good job. I definitely think the shot of the AT-AT firing should be flipped horizontally, I think that would greatly improve the scene.
I think that if you flip the shot then it won’t make sense. It is meant to look like Finn’s right speeder wing gets hit so you would expect an AT AT to be shooting from that angle.
Watching it again I see what you mean. I was thinking that it would better match the direction Finn looks, and the angle the scene is shot at in general. Works either way though.
