Hi there - your 3 designs are very nice. They are ever-so-slightly too playful although we like the implied movement, the hint of ying/yang, and the inclusion of an abstract sun in #180. On the other side, we also don't want anything too corporate. We prefer crisp, clean and sleek. We hope this is helpful and we will watch for more from you. Please see if you can incorporate our feedback and produce some more for our consideration.
