This put me in mind of angel sanctuary though the wings are entirely in your own style. I believe it's just the way you render detail and the sharp but feminine features that you illustrate your male characters with. The snake cup is a great touch
Very unique. A collar of wings? That's the first I ever heard of something like that. And as always, your inking and penning and stuff amazes me. Especially how you work that skin and hair. D: Amazing.
