I like the division into three parts, that works really well in this image. However, nothing seems to be in sharp focus, and the blown out sky makes it look a little like a snap shot.
I would've shot this so the treeline was the foreground. The tall grass takes some of the focus away. Then you could've gotten a bigger image with more details.
I would've loved to take this photo and used hdr and visited it both day and night. You could try that. Would've made one heck of a desktop image!
Interesting concept, the tower is well positioned. The sky's over exposed and has lost detail, the foreground could be sharper, though I like the sense of movement below the hedge
It's a little blown out on top. It's hard with basic editing to get a well exposed field (which you have) and a well exposed sky/white sentinel in the same shot. Maybe try retaking this closer to dusk to get a more balanced shot?
sorry, not enough DOF, too dark in the trees, sky is blown, too much foreground – composition would be much better, if the bottom quarter was cropped off.
