If you want to keep the chain going, as suggested above, the center block on the right need correcting (rotating the 4 patch) to achieve that. I like your colors. I would pull a darker color, maybe a brown that is darker than the star background, or a darker green that goes with your greens. If you sash each block, maybe brown (the color of the star background) around the block with the 4 patch squares, and a green around the start block, then you would need a 4 patch cornerstone. That would be very pretty as well as a single color for sashing.
In all that, I forgot to say, keep up the good work. Your quilt will be pretty whatever you decide.
