Very nice Mike!
I saved a copy and had a look in PS to have a look at the histogram. It looks to me like it could benefit from a bit of an increase in contrast. I had a fiddle with curves and both "increase contrast" and "strong contrast" curve presets in CS3 look better to me on my monitor. Without that, it looks like a white mist/film in front of the image on my monitor.
What curves processing did you do?
