Our Lady of the Rainforest

Because part of the face is blurred, where you placed the butterfly should be blurred. Shadows from the butterfly on the face will add depth. Some shading and shine could also be added to the dots along her nose and bridge. This will help add depth. They look like piercings to me, and if they are, then shadows from the piercings could also be added to make it appear more realistic. The red eyeliner along the bottom of her eye seems a little too well drawn. By blending it and adding some of the skin color to it may make it look a bit more realistic as well. And because this is such a close up picture, you should add skin pores. Her top lip liner is a bit awkward and it makes her top lip seem extremely thin. It also lacks the wrinkles that the bottom lip has.
But, the clear skin is a very nice touch and makes her seem very fairy like. I extremely like the details you put into her eyes and the design for the pupils and iris. The feathers in her hair add a nice touch and reminds me of a tropical bird of some sort. Over all, it's a very exotic looking piece, but some shading and realistic touches that correlate to the actual human face (skin pores and lip lines) would make this seem more realistic.
