That is far too yellow. On my calibrated monitor it needed backing off just a touch on the blue, just enough so that the almost burn-out sky doesn't turn yellow. And a small brightness tweak to lighten up the shadows, maybe. The camera WB wasn't far off actually. You could do much more if the file was RAW
