I'll chime in with something else
I can accept most things with the image as it stands, given you'd acknowledged it may come across as false, but you like it.
The one thing, ok two, I would query are;
the white balance, it looks quite high on yellow to me and
the CA (chromatic abberation), but only where it is most noticeable; the red/green edges on flag pole and the trees against the sky
Forgive me mentioing the CA, I am particularly sensitive to it having been trained as a video camera engineer in the seventies when the broadcast TV cameras (and the first colour CRT monitors) needed that kind of thing manually adjusting out (well, as best you could )
I hope that is helpful, to add to the others views,
