What I found was interesting...Having the purple sections (of the outer diamonds) towards the inside (upper left) left the boundary of the pieced 8 green squares much less defined than when the greens were towards the inside (upper right). This is much crisper to me. I need these pieced squares to be defined and not just blur into the diamonds, like they do in my actual picture above.
I also played with the placement of the center diamonds. Teals to the inside or blues??... Placing the teal to the center makes the center not appear as this bright spot, and the light blue points further help to define the 8 leafy squares. So right now, the bottom right is my preferred layout.
What is your's?...and why?
