I love this picture and wouldn't change much about it. The left side is a little dark -- maybe give it a swipe with the dodge brush. This is a minor nit-pick. keep on shooting. 8
This indeed is odd, but the picture is just too busy for me to focus on the woman. The paintings on the wall and all of the various animals are really distracting from the woman.
Excellant compostion and masterfull tonal control. Only weakness is the fact that your subject is in the 'darker' side of your picture. The picture seems to go from light to dark, from right to left, as shown in the lostt of detail in the red drawing.
I think there might be enough range for a general lightening to work in bringing out more detail, or a gradient adjustment or selective dodge/burn outside the challenge.
I really like this a lot, keep up the good work.
