Entry #15 is a little too common looking, not unique enough. #14 is a little too fluffy (too feminine) I like #`3 the best, this one has the most potential - it would be nice to see some spin-offs of that version.
I am not sure I understand what you mean by static vs. dynamic when it comes to a still design. When I think of dynamic vs. static I think of a flash animated banner vs. a static one. If by dynamic, you mean more complicated? Possibly yes. More unique is what I want. These symbols are more generic - by generic I mean that these remind me of many other logos I have seen, although very well done, they look more like a standard logo you would see on istock or something. Generic as in they could work for nearly any company. I want something that uniquely represents our idea and stands out from all others. Thanks, these are well done though like i said, I am super picky so don't feel bad.
