i went through the last ten pages again... jesus, dude, you're killing it! i like it all, but i think my favorites are the b/w thumbs--you have a nice economical way of sketching them out and rendering them with just the right amount of brushiness. fucking great stuff! and it's really great to see your work ethic and willingness to explain things too. very cool man.
the "thanks" button is broken right now, but there are more than a few gems in these last few pages. rock on!
