I, too, prefer the design on the left; however, If I may make a suggestion, I would flip it horizontally so the bird faces the right. As you know, western printed language flows from left to right; from a design perspective, the aesthetic of right-facing imagery subtly implies a “forward” direction, or moving forward to the future. Considering the purpose of this icon in this new frontier, I think that would be appropriate.

Fantastic design, and I think the subtle gradient you dropped in the background is a nice touch.
