That's starting to look really cool. If I could make a few suggestions though. First I'd move the crown thing back so its sitting "behind" her bangs. Maybe right between where her bangs and hair meet. I'd also retexture the skull from Montezuma to look like it is made out of jade or something and put that where a clasp or knot would be on the cape. You might want to add some feathers around the crown too (like Huayna Capac has). I think the feathers on the shoulders might be overdoing it a bit, but I don't know. The background is a little busy too and kind of makes the LH look messy overall, and it doesn't let the LH stand out IMO. Maybe grab the final image from the Chichen Itza wondermovie and use that?
EDIT: Oh yeah, the face paint is cool, but I think the Jaguar pattern isn't the best choice. I'd go with something black, blue, or green.
