Sometimes you have to put a project aside for a couple of months and then come back to it. Your brain will have thought it all over (subconscious at work) and that might allow you to figure out what you need to change.
I made one, hated it when it was done, stuffed it into the closet, took it out about a year later - and miraculously liked it again. The memories of mistakes had faded. One day I'll actually quilt it...but not yet.
Good luck!
