Toni, I think value is more important than color, and you have a light, a medium and a dark that happen to be green. Look at nature: All sorts of different greens together and it looks beautiful!
The first time I ever tried a block with points I formed the points on the exact edge of the fabric, forgetting that I would be sewing something else to them. And when I did, of course, I lost my points. The point has to be formed a quarter inch from the edge of the material or it will get chopped off.
