Ooh, he's spooky looking. And the black background really makes him stand out. Was his hair naturally like that? I just ask because I have yet to come across any young white-haired men who didn't have either a) some aptitude for magic or b) supernatural ancestry somewhere in their family tree. Doesn't work the other way around, oddly enough. ^^ Anyway, very cool picture. The edges too look a teensy bit jagged but I don't see any 'white dots', so don't worry about it. Here's a trick, though: If you have a computer paint program, see if there's an 'antialias' setting on your area-fill (paint bucket?) tool. Then use it to color the background light grey (not white), then back to black. That'll fuzz out the edges for you. You could also blur it very slightly instead, but that might mess up the rest of your picture.
