very nice,the color minus 3 places is good, his hair and sleeve ends have some funk with highlights and the inside over his right shoulder is too light, bit otherwise great. However given the upper right corner i think you borrowed chapter 182's cover instead of drawing it yourself.
note i'm not saying it's bad to mimic other people's style, that can be a great skill. (i tried my hand sketching this one myself) however it seems to go against the grain to color someone else's work without permission, granted he probably wouldn't care, but it still goes against better judgment. (and probably copyright if you didn't draw this yourself, i'm not saying you didn't but detail stuff looks to exact to me.)
