Thanks for the comments, and thanks very much for the edit, abraxas. Your edit convinces me that I should boost the highlights a bit in the parts that aren't in shadow. I'm not so sure about bringing out the shadow detail. Your taste buds are better than mine, though, so I'm probably wrong.
Mersad, I'm glad that it inspired you, and yours is an interesting take on it. It's understandable that you substituted a more interesting sky. I was hoping for some clouds that morning but there were none.
abraxas, my first work-up had lots of shadow detail. I decided to simplify it by taking the shadows down. I'm always interested in how you would see a shot, though. I've learned a lot from your comments and I appreciate them.
