Welll, I just had to re-log in to comment here! I was browsing todays people/traditional entries to see what my stuff was amongst, you know the usual anime juvinile stuff, and Wooowwie!

my only complaint would be that the hair is a bit light colored but the lighting on the face is fantastic. you did an outstanding job shading his face, and I'm going to say keep up the good work, friend.
