New Logo

Since I've joined Dribbble, I felt like I needed a rebrand.

I was always been known as bart172, a nickname I chose when I was 8, but now I think the time of nicknames it's over.

I'm becoming a serious artist, and the first step in my little revolution is changing my logo.

I've designed my old logo almost two years ago, when I firstly started approaching at icon design, and I've used it ever since.

The new logo is based on five circles and their radius ratio.
The logo uses the two big circles of the iOS Grid and the diameter of the three small circles is the difference between the big one and the small one.

Any thoughts?
