Why that much empty space behind the bird? You could at least filled it with big Moon.
Would have a better composition and story behind.
I, personally, would do it, and even add few birds in flight, with blurred wings, so ayes would travel throughout the whole image and have many things to explore.
This way: follow the river, fish, bird stomach, the beak, than... Empty space and all suddenly freezes. Story ends abruptly.
All composition is awkward. It feels like there was more image to the left, but it was cut on the best part...
