It may not pass muster as a magazine photo but considering what we had years ago, it’s not too bad. Yes, I can see some bulge in the horizon and the sky colours are inconsistent but…. it handles the direct sun well. And, if you consider the effect of some polarizing filters on wide angle lenses where the sky is very unevenly reflected, it’s not a bad result. Additionally, wide angle lenses don’t cover this much ground. Anyway, not much done in post at all. You just have to make surethe image is balanced and you have enough subject matter to fill the frame.
