Your version looks much better. One of my first instincts was to want to rotate it as well, but I kept telling myself I shouldn't do that, to stay more true to what I was really seeing. However, in this case, since the shot was close enough to directly from the side and it is so hard to tell what is going on in the background, I don't think most people would be able to tell that it wasn't actually flying like that. Flight in that attitude is entirely possible. It would just have some forward velocity. We happened to be trying to avoid that for this shoot, though.
I notice that you chose to place it in the lower left of the frame. Was that a function of the directions of the lines on the shape of the bird, or the implied motion of the bird? Is it generally considered to be more pleasing for it to appear as though it is flying into the open space, rather than flying out of it?
You're absolutely right about the realism of its attitude in hovering flight. The angle of the body with respect to the wing flapping plane was an intentional compromise in our design. Unfortunately, it was not able to be driven by aesthetics alone. Real hummingbirds can have an even more complicated wing stroke. They sure are amazing creatures.
