Hmm yes, I really prefer Contest21crop.jpg and feel it kind of veered off course after that. Latest versions have a very green tone to them, and feel very "muddy", compared to the sharp, detailed look of Contest21crop.jpg. If you can bring back that lighting and atmo, then add in the mist (white not green?) and perhaps the overcast-ish sky...
Just my 2 cents, though. Personal preference, no doubt.
