YouTube thumbnail, epic movie poster style. Elder Kael, a 40-year-old ape with a prominent forehead and a stern face, stands in the foreground. The ape does not look at the camera, but looks forward, at a distant, undefined horizon. Behind the ape, stretched out in a long, weary line, is his entire tribe moving across the Desert of Ashes. The wind blows hard, stirring up dust and the ape’s tattered saber-toothed tiger pelt. The harsh sunlight creates long shadows. The camera angle is at Kael’s shoulder, focusing on the burden on the ape’s face and the small group of people behind him. Hyper-realistic, 8K quality, fiery red-orange tones.
