a fully commercial 3D rendered illustration, vertical composition. In the foreground, the curved surface of a glossy silver-blue moon with detailed crater textures and shiny reflections is shown at the bottom of the frame. A cute green alien with an oversized round head and short chubby body stands prominently on the moon, big glossy black eyes and a tiny mouth, making it the main character. Floating slightly in front of the alien’s face is a much smaller pink alien octopus creature, just slightly larger than the alien’s eye. It has a round head with stubby tentacles and tiny antenna-like bumps, glowing faintly with a mystical dreamy light. The green alien gazes curiously at the floating octopus creature. The cosmic background is a simple clean gradient in deep blue with no stars or planets, minimal and atmospheric. Ultra-detailed, cinematic lighting, polished commercial-grade 3D render
