I'm looking at the wrap and the UV map seems a little difficult, you may divide it in more materials so that you can move them on the UV map in the uvmapper. One suggestion: once made the obj file, import it in
Poser, use the "group editor" and "weld groups", the final result is more uniform.
I tried to transform the UV with spherical maps but the result is not fine (first time that I deeply use the uvmapper) even if the result with a planar texture is a little better..
