really beautiful colors!! I agree with those who mentioned the borders seem to be to busy. but then I look at it again and the same blocks stacked in rows seem to not work right.. I wonder if arranging them every other block different then starting with a different one at the beginning of the row might take that feeling that something is not right away.
When I just glance at the picture.. I get an impression that the 3rd block is longer than the 2 before it. I know they are the same but the optical allusion seems to make it look that way.
