I don't know if you are still scanning this for feedback, but I really like the energy in the Amelia logo. The others seem flat in comparison and not just because the are less commercial. One gets more of a feeling up "up and away" with Amelia.

I hope you haven't given up entirely on this. Today I just finished rereading "Horton hears a Hoo" - sometimes it really does take a small voice who hasn't been heard before to make a real change. Until people listen it really can feel dim, but that doesn't mean you are wrong or have something that shouldn't be put into the lime light.
