This is an amazing capture. I've never seen this happen, nor can I remember seeing a photo of it.
In action photos,I understand that there are severe limitations to the control one has over composition. Bearing that in mind, I find the water line to be too strong. One possibility is to crop it out. This means clipping the end of one wing, but I think that the photo would be much stronger presented this way and cropped into a vertical format. Increasing the contrast between subject and water using photoshop might make the image more impactful.
