Bowser
Mario and Luigi were easy, I've been drawing them since Mario Kart 64.  The Toads were simple after I figured out their headgear, and Yoshi came after reading my Field Guide to Dinosaurs.  The Princess was still troubling me but I made some headway with her as well.  But Bowser?  I've been drawing him as long as the Marios. Bowser still hasn't been a final look in the comic.  It's hard here though.  I have to balance the force he weilds and still have him match the style of the series.  I don't know what it is about this picture, but he still doesn't look right.  He's still got that evilness (is that a word?), but it's not the Koopa I'm looking for.  Moo.
