Love the colors. I alter the rail fence all the time. A fave.
I think your quilt is kin to a pillowcase I just finished (with 3 *orange* Valori Wells fabrics).
Be sure to check out the Gee's Bend style patterns. They're coming out soon.

The examples show straight edges and binding but they could be made wonkier like the real deal.
