red-skinned bat demon warrior

A massive, muscular red-skinned bat demon warrior crouching in an aggressive pose. He has red reptilian scales on his skin, a black leathery cowl on his head, sharp tusks jutting from his lower jaw, and large leathery bat wings with red membranes behind him. His arms are huge and gorilla-like with stone-like dark metal armor on his shoulders and forearms. He is standing inside a gothic library with wooden bookshelves in the background. High-end CGI, dynamic lighting, monstrous fantasy movie style.
