Aww, leave him alone. If JJA played anything like JJ1 or JJ2, the new look wouldn't be a problem. It's not like everyone has to wear the exact same thing all of the time, and the new art style is actually just a bit nicer. It's because everything else about it is different that JJA isn't a true jazz game, not because of what he looks like.

I personally like the way Dodril draws Jazz best though.
