I like King's black costume, Feng's is pretty stylish as well, Hwoarang got his old hair back, Xiaoyu's costume is meh. The levels are pretty good but not really amazing, the faces could stand to be a bit more expressive (like SC2) but then I guess you don't get a full idea of that from screens.
I still haven't seen this game in motion, did they make it more flowing? Tekken 4 was a decent improvement, but still several steps behind other new fighters..
