This is NOT a criticism! I've never done a pinwheel quilt ... probably not even a pinwheel block, but I notice that in each of your 4 blocks, you have the smaller triangles reversed on the right sides to what they are on the left sides. Is that how they are supposed to be? (This is a serious question I'm asking; I genuinely do not know.) In other words, do you have one of the halves of each pinwheel block upside down?
