Sweet! Kaneda (hee hee) with the rail gun would be pretty cool, or a still from the anime recreated in your style (like the Daredevil cover you did a while bk?) would also look awesome. Ooh, how about one of the posters? Like the one with the red text on the white floor and Kaneda + bike? There were some seriously awesome posters for it thinking about it actually..
... Really need to get the graphics and read them (hangs head in shame!)
