|Altered Image #1|
|Rotated 1°CCW to align it to the guide lines in the centre of the web.|
Cropped off the top and bottom to accentuate the area of interest IMO.
Increased saturation +15 to add a bit more bite, along with minor USM (50%, 10px, 0).
Finally added a little vignetting using Filter/Distort/LensCorrection +35 darken.
Just an idea :)
