Nice, crazy compostition! Love the details, the feather-things must have taken forever to draw. My only little complaint would be: I'm not so sure if I like the shading on her front.. Now, I'm not being a perv here, but maybe it's because she hold her arms up, so her breasts doesn't form a crease underneath them.
I love the details you made on the background and on her leggings. The way you did the shading are amazing how you blend the lighting and the shadows with the basic colors. Overall, your work really stands out with your style and the vibrant colors.
