First, let me congratulate you on placing in the top twenty. Technically, your image has been captured and processed to perfection for my vote. I love how the composition with the two windmills gives this image so much depth. In my opinion, the only thing keeping this from winning a ribbon is that the clouds are a little low in the sky (Which was not something you could not control). If they were higher, the sky would have been much more dramatic. You could have also made the sky look more dramatic by increasing the saturation just a bit but to me, that would have looked over processed. However, over processed skies do score well at DPC.
Feel free to PM me if you have any questions regarding this critique.
Love the colors... IMHO the picture would have looked nicer if the windmills were pictured from a more interesting point of wiew...??? but, I do like this picture... Good luck :o)
