I enjoy the detailed simplicity of this piece. The smoothness speaks to the calm quality of the piece. The body's neutral color compliments the pastel explosion at the top of the head. I really enjoy the body posture and the shading. It's very nicely done.
My only real criticism is that the blending of the hair into the pastel colors is a gorgeous touch but I think it might have been carried through a little better. See the harder, darker lines along the inner petals - that's where I think it could have been softer.
GORGEOUS work all over! It was an organic piece that really did what you wanted.
