I love that style. I must learn it. You do a really nice job with your avatars, Akasha-chan. You're almost as good as Pavo. I hope you keep displaying your work to us because these are amazing.
If you can, would you mind sharing with me why you made them dark? It's not bad but usually when people do it like that it is because they are either going for a desired effect or because they are aiming to learn something new. ^_^
