Wow, this is really one stunning pic. And this effect is done by this aura which makes her look even more evil. Black Lady was one of better thought and build villian in all series. From character point of view as well as colour scheme. You really make quite effort in that dress although I don't remember her to white layer under the black one but let's leave that aside as artistic interpretation. Deciding to make source of light not from back or from front was a bullseye, which made the possibility to showoff her curves. Also what I really like is that you make the shawl without lines just the colour. The only thing that I could say looks a bit off is her neck and head. Not propotion not coloring but that it looks stiff. As whole her body is really flexible and looks natural in such a pose her neck is like sticked to the rest. But the rest is great .
