Beautiful. The out of focus thorn in the foreground seems out of place. I wish there was more of it or none at all. As it is, it's pretty prominent and cuts through a huge part of the photo. Worse, although it helps frame the subject, it dramatically emphasizes the leaves on the left (almost like an inset), and they don't deserve it (not well lit, not in focus). This would be the area to put your logo or descriptive text. Perhaps aggressive cropping would help.
Stop action on a Hummingbird is quite a feat! Scene is a bit busy; if it was possible to use a shallower DOF I would have. But I'm still impressed with the capture.
