@Joseph - Yeah, I understand what you mean now. Sorry, I completely skipped over your suggestion. The shirt is looking awesome, so I may consider changing what was meant to be more of a poncho, into a leather jacket. Something about it, though, changes the overall style, so the head no longer seems to fit with the rest of the piece. Anyway, I'll definitely have a revision up tomorrow morning, as it's getting really later right now.
@Akzidenz - I just noticed the ninja mask you mentioned. To me, it initially looked like the hair (and that's obviously because I wanted it to be a part of the hair) but from a different perspective...
Also, there are no palette restrictions; this is just a personal piece i'm thinking of creating a sprite sheet for. in fact, I'm thinking of scrapping the vespa idea, and go for something completely different. I couldn't think of many ways to use a vespa throughout the whole game.
@BOB - Damn, that's exactly what I've been wanting to do. Not too fond of the hair, but it doesn't look bad either. There are so many ways to go with this piece now.
as i said, I'll get on some edits done tomorrow. Thanks for the suggestions guys.
