This is a stunning shot! I love the ferocity of the action and the overall composition. I feel kind of sad for the animals, with those hooks in their nostrils like that, but you've captured a unique moment, for sure. Well done!
I don't believe that taking a photo has to have a moral justification. It does not necessarily advocate for cruelty. It can inform to take a picture and that is a good thing. An even better thing if it is done well.
