it is a nice photo but it looks a bit flat to me
here I warmed it up in camera raw by +2 set the recovery slider to 44 ,-2 contrast and a +28 clarity,
Then in Photoshop Used 0.5px of highpass sharping and added a contrast curve to adjust the contrast rather than attempt it in camera raw with a low res file for the web.
