I love your photo! The difference in colors is striking. I wonder if you could add some more contrast to make the differences even more striking. Just a thought. Beautiful photo!
The submission is too small to be properly critiqued, and the image itself has absolutely nothing to do with the theme of the challenge. It looks almost as though you just randomly chose a picture from your hard drive that you liked.
I think you'll find that bigger images get better scores. Try to use all the pixels available to you. I like the lines of the hills and the colors. I'd like to like the detail of whatever's growing but I can't make it out.
I really like your use of layers. It would probably have been terrific though to have some foreground here like a flower or a person sitting in the grass.
I guess a lot of people will comment on the small size of the image ...
