If you made the guys look like they were running into battle, it would have looked better. Also, I don't know how extencive your collection is, but I know I can't make big battle scenes like these, so I stick to making ships and smaller vehicles. I think you did a decent job on getting a more realistic situation by having plenty of clones and droids to battle it out.
This is a great MOC I also agree with Thomas though needs some more detail to help getting more people to comment and rate on your creations is to add people to your fav builders or ask other people to comment on your creations. 4/5
