I am also a bit colour-blind. Why could I not be interested in mucking out horses, or shampooing poodles?

Photography, or rather processing / printing is hard enough as it is...... Maybe this is the subconsious reason that I always liked black and white. (And is my excuse for c**p photographs)!!
Anyway, back to the subject. For me, the low dark central cloud is the spoiler. This, the central horizon and the track running up the middle give the shot four quarters, and I guess that bothers me a bit. I think the clouds are a bit distracting. Scroll down so the browser window takes out the darkest clouds, just leave a little sky in the shot. I think it works better.
Perhaps with some foreground interest and less sky, the track becomes a mid / background feature, taking you through the landscape.
Still a good picture that I'd be pleased with.
