Honestly, this is a photography forum, not a photoshop forum. You may get better results asking at a photoshop forum... and besides, a good photographer should know how to draw out the most from their equipment so that little to NO photoshopping is needed at all to get a wonderful shot.
There is some exposure or light sharpening needed there, but the photo itself has a few flaws that limit what most could do becuase the technical aspects are not as good as they could be.
I am sure a master of photoshop could spend lots of time and make it look good... but why? The right way (in camera), would have been to get the shot right in the first place.
Technical aspects that I speak of are things like:
- the strobes are in the wrong positions
- the exposure is not set correctly
- the pose itself is not flattering of the model
- the specular highlights on her face are not very helpful
Thats enough for a start.

I hope that helped some.
