Those thigh-boots look really awesome, I just hope they aren't cutting off her circulation. They look a bit tight.
The attention to detail and the thought put into this is solid e.g. the slack of her outfit on her raised leg is a nice touch.
Is there anything you'd be willing to share about what influenced you on this one? I saw Soul Calibur mentioned and I can see some of that in the gauntlet.
Also, any kind of story come to mind when you were making this lovely mistress of death magic, or does she not really have any background to speak of? It's just that such a complicated looking character makes me want to ask.
