eos M 10 samyang 8 mm fisheye
I don't think the fisheye looks the best choice for this scene - it's given you big exposure problems which you've tried to fix in editing, but rarely does burning blown highlights ever work and you can see where you've tried to paint them back. It's generally best to try and keep the sun out of the frame, and a longer lens would let you concentrate on one area of the scene - the mountains to the left are an obvious shot as are the trees to the right, but both together there's a big empty area in the middle of the shot and nowhere obvious to look. The foreground isn't working for you either, better to eliminate if it's scrappy
I like this but i would have cropped from the bottom of post on the left downwards.
I agree with Swissy about the crop, I think it would benefit from it. I like the cool tones and still water. Your photo is really clean and portrays the coolness of the scene very well.
Looks like it's a location with loads of potential for further compositions.
thank cmcm ...very kind...
