While I love the detail that went into the body and I think that potentially makes it strong. However what ends up being a huge detractor for this piece is the anti-aliasing that's used on the outlines for your character mainly because against the background it distracts more than it adds anything to keep the viewer engaged with the piece. If the pixels used in the anti-aliasing were in a light background or if it was adjusted with some level of transparency to work with the background then it might actually do it a favor in this case.
I do like this. At the same time with the problem I have with it is keeping me from giving this a full five stars.
