Trouble In Paradise

This painting is making me bananas. When I see it, I want to throw things at it. Amongst whatever else is wrong with it, it's now overworked, and I don't know if I can save it. It bums me out, and I hate to give up, but this could be it.

It was the first painting I attempted in this landscape series, and so it was the least clearly defined going in, and I KNOW that not every painting works out... I just hate to be a quitter.
