Nice subject matter to work with. I think the advice given by Ken is spot on.
Go for the clean image with good exposure and composition and let your image make its own statement - leave the digital acrobatics to others who are really into that sort of thing. Certainly this is advice I am taking on board for myself.
A good shot, like a good idea (or a strong melody in music), will stand out almost irrespective of the post production treatment many times and in my humble opinion many people kill great photographs by over manipulation in PP. You see it in all the photography magazines where they feature shots with very heavy skies and different effects and I wonder sometimes that if I went to that location would it look anything like that. I think it is digital overkill.
It's a bit akin to modern hip hop music which is so overdubbed and over produced in the studio (digitally again!) that they often lose the 'clean' sound and truth of the melody and can't reproduce it in real life without a backing track.
This obsession with over production in music has also meant that they have lost the 'quiet bits' to in modern music and have to fill every space...I think this is what is happening in digital photography...sometimes silence or minimalism is golden
Frequently less is more and I think in this digital age it can be quite brave to be minimal in your pictures and get back to basics.
there I've got it off my chest, sorry for rambling and if it appeared like a rant, but it made me feel better
I actually liked the colour version and think that worked better than the over processed one. Although Paul did a great job on it giving it more contrast
Personally I prefer black and white photos with good contrast, strong blacks and bright whites, and the first one seemed a bit muddy...could I have done it any better? I doubt it
