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:
