Full Circle Brand Mark

I am finishing up the identity design for a fine art & photography service provider. We wanted to design a simple modernist mark that captured some of their service offerings (like framing, printing, reproduction, fine art, etc) without being too literal, while achieving a little bit of an "ah-ha" effect. The "F" shape stands for Full, while the circle is, well you get it.

Once we had a solid concept, I pulled out the trusty golden ratio spiral to help bring harmony to the proportions and design. You can see the progression of the design here. What do you think?
