your first vector? wow, it's so much better than mine...
anyway, nice work, it's really smooth and clean :)
and the shading looks fine to me. I esp like how you did his eyes ^^
yeah those pics are more like sketches, so the outlines and shading is rather quick and sloppy, but I guess it's just her style.
nice work! can't wait to see the rest :D (you're not doing Hanajima and Arisa?)
