I like the shapes you are playing with in the pencils. Colored pieces are good too, they have nice muted colors. I think your pencils would benefit a lot if the lines were more confident.
Actually, I'm really interested in the artist for the Morrigan piece you posted: http://img226.imagevenue.com/img.php...123_445lo.jpg#
I can't find the artist because Choco is a terribly common name; I have some doujin from a Choco but it's a different style (and I assume different artist). Do you have any more information ?
