No shading

Something new, something interesting! In my humble opinion, the style resembles to some extent what is often called "simple" style. This style's artworks are usually made of non-outlined 2D shapes which gives the final product a very "simple" yet interesting aspect. Even though the depth is less explicit, if the artwork is made with enough care there should be no problem conceiving it. I would simply like to warn you about more complex scenery with many characters, since the final "simple" style result might get confusing because shapes are not outlined. Grosso modo, for images containing one or a few characters, this style is actually quite interesting since it also lets the viewer imagine some part, or dimension, of the artwork. About, your deviation itself, I think you did a very good job at it with cautious layering and some fancy accessories. There is also something which I find quite interesting... I don't know if it's just me, but there must be a reason you chose to remove her pupils. Removing such a "vital" part really gives the artwork a much more abstract nature, which I totally agree with since it "simplifies" the overall allure of the artwork a lot. The resulting effect is impressive. I cannot wait to see some more.
