Definitely nothing to be ashamed of in that quilt! It is lovely. I love that you got the look of points by using contrasting colors in all the right places. I think it is only noticeable because you have it laid out on the floor. You will probably never have it laid out perfectly on the floor like that again. No one will ever notice when it is in use.
I know we quilters can be hard on ourselves. I used to have trouble with wavy borders. I don't have that problem since I started using Bonnie Hunter's technique for borders.
Here is the link to her instructions.
