I have to applaud that work! Posterization by hand takes forever. I once posterized an ad for a color palm pilot to gray tones. It was funny, 'cuz the ad said "Pure color" heheh. I actually have a crit for this-- the pure white highlights on his skin seem kind of out of place with all the nice warm colors in the rest of the picture. It almost looks unfinished.

hooray for non-cgi images! this is excellent painting! good style for a poster too (is that what posterization is?), it'd be pretty easy to reproduce and stuff.
plus guys in black tie and white colar shirts is one of my favourite subject matters. i like the blues brothers look, don't you?
