I worked on this over the last couple of days. It is supposed to be James Marsters as Spike, from Buffy: The Vampire Slayer.
I like a few things about this piece, but I really dropped the ball on his ‘do. Too much outlining of the hair.
The hair looks less cartoony, but I don’t think it helps the likeness. Spike had spiked nearly-white hair, and this is too dark.
