Another try at "plant in a landscape", taken recently.
sun: too much? exclude during composition? wait till it's further down?
lens flare: remove?
wimpy trees on the right: exclude during composition?
It's a very pretty image. I think it would be improved by all three of the suggestions you yourself make. The sun is important but there's just a bit too much of it, which I suspect would be less of an issue were you to wait a short time - a few minutes only, I'd guess. A small crop on the right wouldn't hurt. Of the three, the flare is the least troublesome.
