So many of us are birds of a feather and we flock together in this obsession with the craziness of "random" placement.
We "get" each other. I did a string quilt once for a baby and I thought it would be totally fun. It was until I started realizing that some of my blocks had dark strings in the same place, which meant they'd visually form 3/4 of a box.
That's the only thing I would change in your lively, fun quilt. Block 6 C in the photo above touches 2 others, forming 3/4 of a blue box. Scatter those out a bit and I think the eye wouldn't zoom in on it "complete" the 4th side of the box. Hope that makes sense.
I have a jelly roll string quilt WIP on my design wall right now. Wish it was as easy to just put the blocks row by row, column by column, stitch by stitch and have that settled feeling when I look at it. But we are designers. Details matter. To some people they matter more. It's definitely a brain thing, not a character flaw. Does it impede productivity? Yes. Are we as prolific as others? No. But we are who we are, and our souls find rest when our eyes are satisfied with order.
I don't call myself a perfectionist. There is a difference.
