Very nice! I like using telephotos for landscapes, because sometimes the whole scene is not as interesting as some parts of it and telephoto helps capturing those parts or details.
But, you have some notable halos at the transition between rock and sky plus oddities in the trees, both of which in my opinion come from aggressive highlight restoration and shadow lifting. I don't know your sharpening settings but those might also play a role.
The hot yellow blob at the top left is also disconcerting. With the exception of possible blown highlights with zero data, I think all are easily remedied with a little judicious processing.
Well, you can also clone skies sometimes, to avoid clumsy transitions to utter white, if warranted.
