This is my actually “wip”
Not too fond of the bright bg, though it is a nice contrast. Obviously the biggest problem is the hair, I would cut the ones on the left shoulder, but more importantly fix the alpha problems and graininess. I would imagine this dude doesn’twash often, so clumpesd and matted hair might look good. I love the nose, wow. Lips look nice and stylized as well, he almost handsome in his funny way. The eyes need work.
Great job, keep it up :).
