My 2 cents: the bird is a little stuck into the corner, so maybe move him a little to the right? Also there are what appear to be two out of focus sticks protruding into the frame which don’t add anything to the image, and therefore they detract. Other than that I like these kind of simple compositions. You have a nice bit of action, and a fish in the beak adds to the story. Definitely it’s an image with potential. That new lens sounds like a load of fun!
