YanYan,
Congrats on making it into the top 5! We like this logo, but it is a bit ethereal, and looks a bit like a question mark (but not completely) or a P (but not completely). The design is really interesting, but it is unclear what this logo is trying to say. Please revise and submit a new version of this design, and try to incorporate some sort of recognizable, easily translatable message and purpose to it. Thanks!
