I like the newer arrangements better because of the symetry, but that's a personal bias. They look as if they're a lot of fun to play around with because you get such different variations. It seems to me if you reach an impasse and don't like arrangements that you can get out of this combination, maybe an alternative would be to use the different block designs in separate quilts, table runners or wall hangings. Among these I adore the mostly white and pink star blocks and would prefer to see them in a setting where they don't have to compete with the other two equally strong blocks. Maybe just put some sashing between them. I'll admit that my version would be a lot more tame, but that's just me.
