Depict the tense atmosphere of a cosmic warzone in the Celestial Arena, where dinosaurs face their end against a dark matter energy alien race. Implement a cinematic DSLR camera style with a telephoto lens to focus closely on the details of the dinosaurs and the subtle manifestations of the alien force. Use slow-motion effects to dramatize the battle scenes and enhance the photorealistic quality. Maintain a raw, unedited visual style to capture the rawness of the battle. --style raw
