very nice... the only thing that I dont like is the lineart for the legs... It looks like it could be cleaned up a bit... but other than that, awesome job! I seriously cannot draw lineart with one pixel brushes, so just ignore me... Well, one tip with that: use the antialiasing function for 1 px brushes, and put the opacity to about 225 or 200 even... it will make smoother thin lineart :D
