This is just beautiful! Love the colours and textures used. The overall composition suits it well. I quite like your style of drawing the human anatomy. The only thing I'm not entirely sure of is how small the hand is to the right hand side. I'm also not 100% sure of the way the feet were drawn - at first I thought she had really large ankles but I later realised they were her actual heels. I think adding some bumps in for the ankles might help. Other than that , I really love the way you did the lighting and shadows on her skin and hair. Fantastic work!
