It's ok, but I feel as if the contrast could've been better, like on the left of the sig. Imo, this would look better as b/w and without text, and maybe Sasuke should be sharpened a little. I really like the right side though, brightness fits there.
Hmm...the text could be blended in a bit better, and Sasuke could be more focused (He looks kinda washed out actually). As far as backround goes, the right side ish better than the left. I would try and make the left side more like the right side.
Overall, it could use work, but it's not a bad sig either. It's somewhere in between.
