Hey guys! I drew this yesterday after not touching my tablet for about a month and I'd like to know what you all think.

It's way messy and I need to study lighting a lot more, but how is it overall? What looks good? What needs more work? Help would be very much appreciated. Like, I really want to make the shadows of his eye... spaces... um, area-beneath-the-eyebrows a cooler color than it is now. Would that be a good idea? Also is anybody familiar with blending in Corel Painter Essentials 3? This is my first time futzing around with it - blending I mean, not the program. But yeah. Critique would be awesome.
