A t-pose shot of a tall, grey alien with large, dark eyes and an elongated head, standing in a desolate, rocky Martian landscape at twilight. Dust motes visible in the thin atmosphere. The alien's skin has subtle textures, showing slight variations in tone and a hint of an otherworldly luminescence. Its long, slender limbs are poised, as if observing, with its three-fingered hands slightly extended. The background features a distant, hazy Earth visible in the sky, and subtle alien structures or ancient ruins partially obscured by dust. Lighting is low-key, with long shadows cast by the alien, creating a sense of mystery and awe. subtle details, and an atmosphere of quiet contemplation and momentous encounter. Shot with a prime lens, shallow depth of field, cinematic quality."
