It looks nice now! It funny how different people "see" different parts of a quilt. I always wonder what my work looks like through other people's eyes, and if they're seeing things that I don't.
I think that as you join the blocks, the green might diminish somewhat. I've done a couple quilts that rely on flow between blocks, and they looked really disappointing on the design wall, but great once assembled. I can't wait to see the finished top!
