I know how you feel, taking it apart and re-doing it. I had the challenge with an Album Quilt which I thought could be a lot better. So, I re-did it, and just have to tie it now. It just wasn't my best.
I also had a table topper with the Amish Pattern of a large center block, and all hand quilted. It had the cornerstones of Amish Blocks and looked really good.
Decided it could have been better so took it apart and re-did it. It was still pretty when I got it done.
Don't worry; I now just do my best work the first time!

All of the suggestion looked very good to me Can't think of anything to add.
