Actually, I like the left mountain being brighter. After all, the sky is only partly cloudly, and the sun has to shine somewhere. It's true that having the lightest area at the edge leads the eye away, but after all, that is the nature of the landscape here.
The foreground and mid-ground could use some color adjustment. Can probably be done as glazes in oils, if you have transparent colors. Don't do this with white or with Cadmiums, or other opaque colors.
The foreground flowers are a bit too crimson. I think they look better as scarlet. This can be adjusted with a very thin glaze of a transparent yellow or yellow-orange. Actually, the glaze can be applied over the entire foreground and midground, right up to the base of the mountains.
I also suggest that the midground be de-saturated a bit, with a slight hint of cyan in the distance. Could be achieved with a very thin glaze of whatever color you have that is most transparent neutral gray, with a hint of cyan.
