Long distance flyers tend to have a long wingspan compared to their body size. The creature you drew wouldn't able to cross oceans and continents like an Arctic Tern. It seemed more suited to live within an ecosystem. Honestly, my first impression was of a somewhat parasitic creature.
If this thing is a hunter of forests, there would have to have some kind of a huge creature like a sauropod or a Paraceratherium walking around. Those claws really suggest they tend to attach to something and the body plan don't support the idea they are able to climb on their own much. Also, the long beak suggest they aren't the primary predator of their ecosystem...herons aren't the ultimate predators....
I suspect you wanted it to resemble a Romulan warship as much as possible...the creature you drew is definitely not an apex creature.
I get that you may not be considering such variables, but the creature you drew definitely isn't the top predator like a wolf, lion or a shark.
