I know my laptop screen isn’t a very good judge, but to me that photo looks a little bit “dull”. I popped it into GIMP, and edited the levels a bit to give it a little bit of “pop”.
Go to Colors > Levels in GIMP
See the attached screenshot for the settings I used. You want to move the white and black points just enough that you don’t “clip” either end. (Don’t move the little arrow beyond where the histogram starts and ends…)
I also sharpened the photo some with the wavelet-decompose tool.
