I really like the new designs, very clever! #5 is my favorite, it really stands out with the black background. What's the difference between #5 & #6?
One concern I have about # 6 is that on a white background (like #7), the design has less of an impact due to the light colours. Is there something we can do to the light color sides of the stones to make them stand out more?
Still, a really cool design.
PS. I don't see the new entry for the first design (that has the transparency removed in the buildings)...was #6 supposed to be this revised design?
