This is an interesting design... My one thought / concern is that the design kind of reminds me of the old game "Pac Man" (although I loved that game when I was a youngster!) If there was a was to soften this up a bit so it doesn't have the Pac Man, look, that would be great.
By the way - I'm new at this service so my apologies if I'm not following the correct protocol but I'm trying to learn! :)
