Interesting submission... I've always liked your style.
I do agree with SeaJae however; the lighting is slightly off.
Honestly, this submission would look better if toned down a bit. There is too much contrast, in my opinion. It makes it appear "foggy." By adding a little bit of clarity, I think it would improve this piece greatly. I'd go with a gradient style of color-shading, preferably using a blend of darker purples and a tad-more black.
