It’s very good! Subtle but it works.

Though, while we’re on small tweaks, I did think of two possible improvements to the following moments.

The first is the shot where the AT-AT fires on Finn. The head should really be tilted down and to the right, since he’s so close to the cannon at that point. Of course it would be impossible to significantly change the position of the head, but perhaps it would be possible to warp/adjust the position of the body to appear as if it were filmed more from the side and level with the ground. There might be a shot of a walker from this angle which is useable for this purpose.

The other is that when Finn’s speeder is hit by the blast, there’s an explosion sound effect on the shot of Finn in the cockpit where he reacts, then there’s the wide shot of the speeder being forced away from the cannon, presumably by this blast. However, it happens so fast that there’s really not enough time to register the explosion before it’s over. My suggestion would be, if at all possible, to add a blaster/shrapnel explosion behind Finn’s speeder in that shot where Rose’s speeder would have been. Perhaps it was the crumpled gun of the speeder blowing up or something else, but there should be something which has the force to divert Finn’s speeder like it does.
