(I just reread my post below before hitting Submit, and it feels rather critical, but I want to be clear - I think your quilt is beautiful! It's just interfering with my OCD, so I thought I would post this in case you wanted to look at a different aspect of the layout. Please please don't let my little weirdsies diminish your amazing work!)
For me, they're all a bit asymmetrical, so they lack the flow I associate with a storm at sea. Your diamond blocks are all arranged consistently (I think that's what you were asking for input on), but the square-in-a-square-in-a-square blocks aren't pointing in consistent directions. This makes the areas where the dark fabric meets up inconsistently shaped, which is where I find my eye being drawn.
