Frank it's a lovely image but all you need to do is adjust the levels in PS.
There's some vignetting but the rest is great.
Here's what I did:
In Photoshop goto: Image | Adjustments | Levels
Adjust the midpoint box (Input Levels) from 1.00 to 2.34
That's it.
From there you can muck around to suit.
Good shooting.
