That blue for reflected light isn't really working man. Looked better without it, not sure if the reflective properties of skin would be that severe either. Unless it was really wet, and was under very certain lighting conditions.... I'm pretty sure that shirt would need to be made from different material too.
The anatomy is really weird, torso isn't wide enough (especially at top) also looks a little too lengthy, legs look weird (especially at shorts). Keep at it though, man. Did you use reference?
