Very interesting shot and crop. Not sure I'm crazy about the border (as I think it's off just a shade or two from the main red colors in the image). Bone certainly has a distinctive texture, as do beads, feathers, and paint. I like this, although I think the right side is a little too dark. I think you could lighten it a few levels, getting more detail from the subject, and without losing the beautiful contrast of light & dark you so artistically chose. Nice work.
