1. I still have no idea how the submission from FROGS won the task. It is a number 6. With little line markings around it -- no idea what that is besides a "6". Very. Unthematic. Totally not an icon I want. (See? I said it would be blunt straight honest opinion coming out)
FROGS' six is a very muted, clear design. Its uses of black, gold, and green give it a regal aroma, which is complemented with the crown and gems to the side. The filigree to the sides are there to look good and add some complexity into the design, which they do.
It won because it's not a tangled mess of wolf-eating-spaghetti, a garish mess of red letters on grey text, or... Whatever S7 made.
(Inb4 this discussion turns into flame wars over icons
Can my demoncow be my forum brawl win instead)
