I love the design and have something similar in the works but using the kaleidoscope block.
I just finished a quilt using Stonehenge which is one of my favorite fabrics. The only thing I would caution you on is that there can be a wide variation in color in the yardage. I was using a deep mossy green and in some places it's lighter and more mint green while in others it's darker and more olive. It was a pretty significant difference. It can also work to your advantage if you fussy cut for some of the variations in your design.
I can't wait to see your progress on this quilt!
