It would be nearly impossible to get a better action shot of these wolves. There was either a lot of luck or careful planning or both. No matter which, it is a job well done.
It is mentioned in the photo's description that it has not been edited. Some edits to focus attention more on the three airborne wolves would be an improvement. The wolf down in front is looking directly at the action, so he helps focus attention on it. But the wolf in the back is focused on something else, and it ever so slightly distracts the viewer from what should be the focus of the photo.
It is unclear what cropping if any has been done to the photo. But perhaps cropping the picture down to just the three entangled wolves and the top (head and back) of the wolf beneath them would narrow the focus of this amazing action shot to include only amazing action.
I really enjoy your work here and hope my review is helpful in at least some small way! : )
I have to agree with almost everything SirSavage said. However, if you decide to crop I would suggest you go from the original bottom of the photo all the way to the top. Only cropping out the wolf who is leaving the shot. If you kept the picture itself tall and narrow it would echo the tall narrow shape made by the three airborne wolves. The shape is further anchored by the almost tripod shape made by the standing wolf. Taken together, the standing wolf and the three others make a tall narrow triangle ( roughly, of course) which is a very visually pleasing shape.
Over all, it's an amazing shot. You should be very pleased with it.
