|*Hello from Sid and the Critique Club*
Congratulations for your high placing with this appealing landscape that meets the challenge well.
A classic scene captured in a classic way, this popular location once more delivers the goods! In terms of the challenge the river is perfectly and naturally framed by the surrounding cliffs. The water is well contrasted with the red stone of the surroundings.
The lighting is fairly flat but conducive to a good even exposure so you have good detail throughout, though the highlights on the water, particularly the left, look close to the limit they are a relatively small but important part of the scene. Your DOF is good with acceptable sharpness throughout. I find the top left corner a little distracting it intrudes in a way that doesn't add to the overall result and looks as though there is some CA with it too, I think it would have been better if you could have excluded it, though it looks as though it was probably difficult. I'm not keen on the red border, I would prefer it without.
Thanks for making such a significant contribution to the challenge, Sid
