Thanks for the entries so far - I like the concept of the bird wrapped around the cloud in entries #2, #3, and #4, however the bird is a little "cute" and "soft". The bird in #7 and #8 is nice.
We also really like the bird design on this site:
http://micro.ilist.com/. If we could somehow make that a little more "Quetzal" and integrated with a cloud.
