Frogmouth helm Knight on his Raptor steed, equipped with lance & shield. Initially, it was going to be a Pachy, but Raptors are much more fun to draw. Next, maybe a Mongol on a Gallimimus? Roman legion on a Syracosaurus? Some sort of siege machine built on a Sauropod? We will see

Also, sorry for poor camera skills & image quality; it’s an old phone at this point
