“A futuristic space base on the surface of an alien planet, designed using the golden triangle composition rule. The main structure of the base is placed along one diagonal, with smaller buildings and landing pads following the triangle’s flow. A glowing energy tower or reactor stands at the triangle’s focal point. The landscape features alien rocks, distant mountains, and a twilight sky filled with stars and two moons. The lighting is cinematic and balanced, emphasizing depth and symmetry. Ultra-detailed, realistic sci-fi concept art”.
