Without knowing the subject of the challenge, I would have been a bit confused on what is the main attraction of the picture. Other than that, I like it. Nice colors.
Nice image and colors. I would crop it tighter... backside cuz there is some distracting light reflections on water and right side cuz something is swimming there :). I think image wouldnt loose much from that.
The composition with the bird on the right is good, although I would likely crop half of the sky out to make the image more dynamic. As is the negative space above the bird is making it appear small and lost within such a large area. By cropping some of the top the bird appears larger in the frame. The colors look a little wishy washy and could probably do with a slight saturation boost. I like the leading line of the post to bird and then out of the frame along the mountain range.
