That really looks amazing! I like the way you make everything seem like its mad of different materials just by a slight different in shading. Excellent job on the hair. I can never get it quite like that. Although, your style does seem simpler than the other styles I've tried to study.
I've been trying to create a style similar to that. In fact I recently did a Asami - in a similar pose no less. Didn't come out as good as I'd hoped. I think i need better brushes. After seeing this I'll have to[link] give it another go soon.
