We absolutely love the idea of the note riding in the paper airplane. The music paper folded was also extremely cool, but we're worried that we'd lose the effect when shrunk down to business card size. This is probably my favorite concept, but I'm worried that it looks too cartoonish. Can you make it look more edgy, less cute?
Personally, this is probably my favorite concept (I'm the president of the company) and could really be brilliant, but my partners are wavering on the idea. Make this next round count! Good luck!
