I have lightened the photo via the levels, it's best viewed in Photoshop; IE darkens them.
Since you said it looked better in Photoshop, I down loaded it to my computer and played around a bit. (It's a slow rainy day here in Memphis.) I don't think it ethical to modify the photos of others and then republish, so I'll just talk about a few editing steps you might take.
First, you can enhance the texture in the neck by using the "dodge" tool a bit. You can also enhance the eye opening in this way.
Second, you can enhance the texture in the white area of the butt a bit by judicious use of the "burn" tool.
I also played around with the "clone" tool a bit in eliminating and modifying the strong white and yellow reflections that others have mentioned. I don't find these objectionable, but they can certainly be edited to possibly improve the image. I think the reflections add interest. The photo goes a bit flat when they are completely eliminated.
I realize that this level of editing is controversial, but I don't see any reason not to do so for artistic photography so long as the intended use does not preclude it.
