Looks sharp and the action is wonderful.
Some things you might want to try to see if they help:
1. Reduce the overall contrast. It looks like the whites on the bird are clipping. At a minimum try highlight recovery on your RAW file.
2. Crop some off the left to alter the dead-center composition.
3. Consider reducing the contrast of the entire background. That would hep the image feel more 3D and it would be less "busy".
4. Try boosting the cyan in the image. I see a bit of a reddish cast on my calibrated monitor.
Dale looks like you have got some sound advice from Henry,my only thought is I would like to see the bird a little more to the left to give the impression of flying into space. Magnificent looking bird very well caught.
