Hi Baco, I like where you are going with the text and font and style... What I don't like is the woman in the pose... It looks too pleasant and feminine, almost like a woman's yoga studio... I'm going for something more neutral.. more hippie, environmentalist, edgy... like Manu Chao ...
#13 I would've raised to my #1 so far if it didn't have the woman but had something else as the symbol.
I like the idea of using the O for the symbol. Maybe you can work something into that O, that fits within the O, but doesn't take over it ... as the symbol.
Lulu lemon has an Omega as its symbol (looks like an upside down U). very simple and sleek
