Nice picture, trees on the horizon are very nice and the sky is lovely. I think possibly you were trying to get to much in here i would have personally zoomed in a bit so that i was closer to the building with the trees in the background and a bit of the wall going off to the right. Might be worth cropping a bit off from the bottom and right of the frame to concentrate the eye more on the trees, wall and building. Foreground is possibly a small bit under exposed also (using a neutral grad would have sorted this out). Nice picture though a bit of cropping and i think it could be really really nice. just my 2 cents worth
Someone else tok a slightly different one of this area a few months ago.
I cannot remember the details but someone else may have better luck, or do i mean a better memory, in case you might like a look??
