Nice job with the modeling. As for texturing I would go along with what vlad said and convert to poly's for the UV's so you can paint it that way. There is one thing about the moedling that threw me for a loop. The stomach muscles seem a little odd. I'm not sure what it is, but they dont seem realistic. It looks excellent and I could be wrong, but I would double check some reference photos. Just my two cents worth. Awesome job overall.
