Please CC on the two versions of this photograph

I prefer the second - the shadows are brought out a bit more and the image feels less flat.

I would do a spot adjustment on the orange part of the sky to bring that down - as others have mentioned, it's a bit too 'hot' relative to the rest of the image.

A bit of straightening would help too.

I think some clarity/structure brush work would help also. I'd add a bit of clarity/structure to the foreground rocks, and subtract some from the far water, to soften it a bit.

Overall, a really good image!
