Some Tips:
1. Anikin has no Schield ( ingame you could just say he gets a forceshield or something like that)
2. The Jedi in the Films always get rid of their Head Robes ( dont know the word ) before they battle.... or they put the whole robe away
3. make the sword rounder and more Lightsaber like
4. Make the head part less like links hat, is doesnt seem like a part of his robe and make the colors "under" his hat ( face etc ) a little darker or you could think its his hair...
