#6 Great concept and creativity. Would like to see an alternate color besides the current version.
Additional thought occurred to me after I made the last comment. In the context of what I'm doing - capture can mean several different things. Capture in writing, capture on video, capture images, etc.... The camera concept is great but may be limiting. Plus, the logo needs to portray the share aspect too.
#33 and #34 - Try it without the bracket around the word happy. Happiness is already bracketed by the smile. In you experience, what color would you choose for happiness? Yes, can try the 2.0 style for effect.
