It’s a lovely image, can’t help but feel you could bring those highlights down a little on the right of the frame though. Not too much, but a little to give a bit more colour.
Highlights are blown in the sky, and perhaps a little bit in the water as well, but this makes it quite easy to drop a better sky. I would be very tempted here.
Possibly still recoverable from the file. All depends how it’s been edited. Personally I’d never drop in another sky.
