My only criticism would be in the contrast in the line work. Each individual part is impeccable. Yet, the crisp, sharp edges of the design in front of her contrast sharply with the softer girl herself. It seems to me that the style of the halo-like pattern behind her head fits her more and is more cohesive with the effect. However, it still looks pretty beast. Despite the differences in shading (I think part of the separation is the almost metallic look to the frontal design, contrasted with the shading on her face and the fact that she is wearing cloth and has nothing else around her shaded in the same manner. There is no other metal and there is a lack of shading on the pattern behind her head. That one looks more like stonework) the artwork is amazing. Did you design the knot that is in the foreground?
