I'm loving it. Others are right about the backgroud fabric pulling it all together. But in the end, you have to like it. If you're still not satisfied, try grouping them together by color. Like all blues in one block, reds, black and whites, browns, etc. Maybe that would suit your fancy. You did a great job. Sometimes, designs have to grow on you. Leave it up where you see it alot. Maybe it will finally click one day.
