I like where you are going with these. At the moment they are a bit too chunky and round. I'd like a little thinner and less round.
Also, how would it look with the black changed to the blue? The above one would look good on the blue background (website) but maybe the reverse would look better on white.
I think I like the new designs - they are certainly very good. I'm just not sure if they will work. #39 is my prefered at this stage but I think I would need it without the mirrorred image. Although it looks very nice I think it adds too much.
