I like the color of paper you used, and the white pencil is amazing in how it brings out a shiny feel for the dudes muscles and armor (I'm no artist, so forgive me if I'm wrong on the technique you used there). Fantastic work!
Saw this on TWCenter, it's really cool. I've had a lame flu lately too, though it actually makes me want to draw less.
I suppose it's supposed to be a Spartan, it's a pretty interesting take on one! I think I'd like 300 more if Frank Miller gave the 'heroically nude' Spartans those leather ptereges 'skirts' instead of jocks, but I'm still looking forward to it.
