Fangman, I think the colour is to do with the colour space that you're using, in the exif it says uncalibrated although if you are using Lightroom it probably sets it to prophoto rgb which is great if you are using it in lightroom and photoshop, but ideally it should be sRGB on the web.
I had this problem a while ago - looked great through the Adobe packages, then it went muddy and dark on the net - changed to working in sRGB and all has been fine ever since.
That said, good shot - just watch they don't get into your roof!
