These new signatures are tiny, but we've still got 500px wide to work with. Try getting a little closer and show off some of that beautiful BOP. Why waste all that space on "just black space?"
I'm sure it could be improved, but compared to everything I've seen so far at the new size, (including my own), I think what you're doing is what we should be striving for. Bold and clean, making do with less "stuff" in our sigs.
I'm sure any second now, someone will come along with something even more amazing, but your signature is striking, and simple, but not in a cheap way. Excellent.
