I like the color, but the background is confusing. Why is there a shadow in the mid section by her hips? She's almost lost in it and it confuses the light source. Considering how intense the light source seems to be, there should probably be more of a shadow down by her feet. Maybe I'm looking at it wrong, but isn't it suppose to be stronger at the bottom and then fade at the top, it seems to be doing the opposite.
I'd consider putting her on a more contrasted background. Her skin is SO dark, yes she's a drow, but the background being as dark as it is, just makes her blend way too much. So it's hard to tell where she starts and ends. Hope that helps. Again, great job on the armor!
