I think the use of a CPL (if you did use one) is a bit too much in this image. The sky is eerily smooth and uniform. This could have probably used a bit of contrast or elevsl to bring some colors out. 6
Color of the sky strikes me as a little too deep of a blue, giving away it's photoshopped nature. At least I assume that's photoshop...if not, I want to move to where you took the picture. But overall this is one of the better pics in the challenge. I give it a 7.
what a great sign! because the red is so faded, and the blue sky so saturated, i would be interested in seeing how this photo would look converted to a b&w. i like the composition of the photo, but the saturated sky seems to overwhelm the picture.
