Conceptually this is very nice, if a bit off the beaten path for a "perspective" challenge. The cropping on the bottom and right is simply excellent. The processing, unfortunately, is a whole other story. It's got an overall muddy, green tint to it that is damaging you. I see you are using lightroom, which is an excellent color management tool, so it makes me wonder if the color is set right on your monitor. Aside from color and noise issues, this is a very nice image.
Very simple very well done,. Not sure why it scored as low as it did. Maybe a bit too much in the blue channel, but not much. Personally I think the photo is a winner.
Interesting and very effective. Breaks the rule of thirds with the horizon, yet still adheres to it with the placement of the trees. Not sure how this straight across composition illustrates perspective, but I really like the image.
