Welcome to the board!
As others have said, only you (the worst critic, lol) see the mistakes. Your daughter not only doesn't see the mistakes, but instead, sees the time and love you devoted to it, just for her. I'm lucky enough to have a daughter like yours - she loves everything I make, mistakes and all!
Finish your quilt, give it to her and in ten years, look back at it and see how far you've come. Happy quilting
