I like the layout and have one question. What is the lower right block?
Edit: Okay. Is the signing block bright like the rest of the quilt? It needs just a bit more color for balance. Can that block be embellished to jazz it up? If not that's okay too.
Another edit: maybe a red flange around the signing block to give some color and balance with the opposite corner and give the block a frame and importance.
I keep going back to look at it and I really like it!
