If you pin/place the blocks touching so that no white of your design wall is showing - any "clumpy areas" will show up better.
Right now, the white showing acts as "sashing" to my eyes.
Then stand back and take pictures - let them "cool" for a while before looking at them.
Tan and blue together is classic - it wears well.
Is there a rhyme and/or reason to the layout? Or are you just going for "pleasing to the senses"?
An aside: If someone has looked carefully enough at something I've made to have found a flaw/error/glitch - I take it that it was interesting enough for that someone to have looked carefully at it. Of course, HOW the person presents their "discovery" does matter!
