I like how much details you put on your art. The colour palette is also nice, but i wold recomand you think of new way of coloring hair - te rest of shading is pretty nice, but the hair doesn't really resemble hair structure,
This is a great piece. Your colouring and painting techniques are very soft yet defined. Overall, I think you balance the colours present here very well, and your lighting is spot on. Great attention to anatomy...nothing is jarring about the posing or proportions. This is a great drawing.
It's a very awesome idea and you draw quite well. My only crit is that the colours start to wash together, making it a bit hard to read. Some value contrast could keep you in the same colour scheme while preventing the washed over look.
