I'm having a hard time with the leap from weatervane to technology although I recogize that we now have weather stations that are very high tech. It's intepretive artistically. The most distracting element of this image is the reversed N-S. Admittedly, this is a result of wind, but it takes away from an otherwise well presented and cropped image with solid contrast and coloring.
This could quite possibly get top 10 but would definately have gotten top 10 had the lighting been better to let out those colors that I know are there. Not sure I dig that lightened area around the weather vane (although that probably makes it stand out as was your intent) -- but that's just personaly preferance.
The inner glow on the border, I don't dig either, your entry stands for itself without some fancy border. Great composition as well, good job!
