That is a pretty shot and I like the presentation of a white background. It's, well, just different and unusual. I like it. Thinking that you probably shot this in landscape mode, you probably cropped out a lot of the frame to the right of the bird. I would use that area to give the bird a bit more room to move into and not have him (her) bumping into the right side. Regardless, like the image a lot and thanks for sharing.
I agree that from a compositional point of view there should be space on the right side but as is, centered on the frame and with the white background, this looks very like it was painted by John James Audubon. That puts it into a category where the usual rules of composition are ignored.
Audubon was an illustrator and had no room on his canvas for anything but his subject.
This, for example, is his 'Fish Hawk or Osprey'.
