Well, one things jumps out: I do not see, why the hair strand at the right top are of the right image are so angular. If this where an output from blender i would suspect the sculptmap is too small (something like 8 * 8 faces). I would expect to see something like this when i used a 32*32 faces map (not an oblong):
The left image is just the untextured sculptie, while the right model is with a simple texture.
