alaskasunshine,
I too, think you need to move some blocks around more. When I look at your first pic., I see 4 that are mostly yellow, 12 mostly blue, some lighter pink, some darker pink, a lot of green ones, some darker than others. If you rearrange, so the colors that are alike are right next to each other, you might find to like the whole thing. Maybe have a diagonal movement happening across from one corner to the opposite corner?
It helps to stand back away from it - like 10 feet or more. The colors in the print change dramatically from looking at them up close.
