The bottom right of 3251 is the part that doesn't work for me. The form kind of fits, but it's very obvious where the dividing line between squares is. My preference is that each level appear as a single image, rather than a set of squares divided neatly by piece.

I'm more interested in Gridcosm when there is harmony.

Of course, it goes without saying that Gridcosm isn't just me. If you prefer it another way, go for it.
