Your design and quilt is gorgeous. There are lessons learned along the way so yes go for round two on your design. You will bring the experience and learn even more this time. It is how we grow our skills.
One of my first machine embroidery projects was a children's quilt that was intensive. Yes, I went back for a second one. Instead of the 103 red lady bugs they were aqua in the second quilt. I was more confident in color choices and walked (or stitched) my own path.
You will always love the first one and there will be room in your heart to love a second one. Enjoy the journey!
