This is an interesting piece. First I want to comment on the anatomy of the figure. I think you did a nice job balancing the femininity of her figure with the more masculine, muscular aspects. She looks powerful, but still is obviously a woman. The abdominal muscles are very well done. The arms are great too, although the veins on the biceps are a little too obvious - some broken or alternating lines might have helped better here. Second, I think the details of the costume - the belts, rings, jewelry, and various weapons, are nicely illustrated and arrayed in such a way that they work for the piece. I also like her face - she seems confident but playful at the same time, and I think that really makes the piece work. As for the coloring job, it's nicely muted and subtle - you're not trying to beat the viewer over the head with a lot of flashy colors and detail work - it accentuates the figure as its supposed to. I could certainly see this illustration in one of the Best of Capcom books that UDON has been putting out. Overall, I would say this is a very strong piece with just a couple of minor flaws. Really great work.
