Adequate fighting and normal birds.
First, combat. A bow with the power of a tank gun is overkill. He is able to tear off a piece from a combat robot. Perhaps a more classic man-to-man war with enemy vehicles, like throwing flammable liquid, would look better.
Second, birds. In the first horizons there were flying robots, but they flew like airships, lazily flapping their wings, which, frankly, hurts the eyes.
Everything is simple here, you need to give the birds a speed of about 300-400 kilometers per hour and in hovering mode let them flap their wings like a helicopter, and show a powerful inductive jet from them.
Imagine a helicopter hovering above you, and such a light breeze and silence in your face. It’s kind of strange, isn’t it?
