I started with an unsharp mask of 150% - 0.3 pix radius no treshold.
Then I faded it to darken with 100% opacity.
After that +5 contrast and a last unsharp mask at 30% - 0.3 pix.
Just that little punch to the edges, without getting those white unsharp masking lines. Hope you like it!
I read the other critique and have to agree the colour is a little bleached, so I set out to try to remedy this.
PP done
1) Level adjustment on red/green/blue as opposed to RGB
2)Adjusted shadows highlights to add a little more shadow (about 12-15% from memory)
3) Pseudo polarisation filter
4) Histogram stretch
Hope you like the result.
