Hi!
I wasn't subscribed before, but got aware of Luis's mockups via
IRC. While I think there's a lot just done right on the website
mockup, I see issues with the logo proposal.
The G in parens concept is fine, but the weighting could be
better. Even then, a G that is all round on the outside is hard to
make harmonious ... and to keep at a far distances from Google's new
G. Then in the lockup, where one paren has to step in the background,
the concept falls apart, to my eyes.
So here's my (first?) proposal, still inspired by Luis's work:
