I think the color differences of the whites make it look like you grabbed several UFO's and sewed them together. But if the colors were the same , it would be more cohesive. I understand that the blocks were added because they have the name "Kansas" in the title, but they should work together. I even think the blues in the background of the flying geese and the pinwheels should be the same. You are heading in the right direction, just a few tweaks will make it wonderful!
