I've got one on my design wall right now. I saw a quilt and wanted to make something similar, even though it's out of my color comfort zone. Don't know if I don't like it because of the colors or what. I'll press on, sometimes I get discouraged at this stage but like the end result.
As far as your quilt, I like the colors a lot, but maybe there's a bit too much going on between the fabric print and the pattern. If you have enough fabric, I would remove the burgundy corners from a couple of blocks and replace them with the same gold used in the others. this way, the secondary QST design would be replaced with a square on point.
You actually don't have to unsew at this point, just cut some of the gold triangle and audition them.
