Was this supposed to be some sort of lip sync test? If so, not bad. ( Oh god another sweater and hoodie clothed character >.<) But that's just me i guess. I guess you used different sprites for the lips. Not bad, but if you could add just a few, slightly more 'in between' sprites. ( Like 2 or 3 that's used to animate his mouth closing and opening.) Then you should be off. I'll see what you come up with next. I'll help you as much as i can :P
