You're heading in the right direction. The simplicity of the 1st choice is nice. It would be better if it some became more abstract - less obvious. The obviousness is fading which is great, but its still there. Power could be derived by having it sneak up on you. What I like about this is that it also feels like a nice wine bottle label. But again, better than nice, it needs to feel powerful. Keep up the good work. Surprise us!
