In a Quandary

I have 2 problem quilts and need some advice. The first is called Fantasy Garden and is entered into our local quilt show that will be held next month. I was happy with it and almost finished when I realized that it's so out of balance. The dark at the top is too small, I think. Short of cutting it up and redoing the background, do you have any ideas that will save this quilt?

The second quilt is the "Tulips." I began the thread sketching, but it's just not right. I can't put my finger on it, but I think it needs something else. The yellow is too bright and too defined, I think. Any ideas?

Thanks so much for your help!
