I've been looking through your work, and I have to say, I was kind of skeptical over whether it would be widely accepted or not, and this piece here certainly is a good vein to be in. When you work in color, it's kind of... a wide pallet, the color choice doesn't really have much of a sense of cohesion. This piece right here is bloody beautiful, but there's always room for improvement.
The bodies need a clearer sense of form, overall-- and color needs cohesion, but you're certainly on track to something really great.
I'd focus on anatomy studies, and color to begin with, and gradually move into hand-drawn backgrounds.
