This is a perfectly nice picture. Despite the often polarised opinions here, there is no good reason that every photograph has to be a solar-plexus wrenching, gob-smacking work of art. It all depends on context. This sort of thing is what I often call a "calender shot", which means that it will make a very usable magazine illustration or library shot. My own local newspaper would love it, they run a picture just like this every day as a half-page spread (and they pay money for it). Addressing your original question, as to post-processing, well you have got most things right - it's in focus, things look level, and the colours are very good without being obviously over-saturated. The only thing I might do in LR would be to add a grad filter in the sky, just to darken the top of the frame by a very subtle amount.
