Square cinematic space selfie with mirrored sunglasses AI Image Prompt

Create a hyper-realistic square cinematic selfie portrait of {argument name="subject" default="a young adult man with olive skin, dark wavy messy hair, a full trimmed black beard and mustache"} shot from a low upward angle, filling most of the frame from chest to forehead, with a serious neutral expression and lips closed. He wears oversized transparent rectangular acetate sunglasses with green mirrored lenses, a white crew-neck T-shirt, and a black tactical-style vest or backpack harness with visible straps and buckles. The mirrored lenses reflect a vivid surreal landscape with green terrain and bright light, like a tiny sci-fi world inside the glasses. Place him in outer space against a dramatic deep-blue star field with glowing nebula clouds, countless small stars, one large blue planet or Earth-like horizon curving up from the lower left, one dark moon near the upper left, and one smaller moon on the right. Use crisp photoreal skin texture, detailed beard hairs, glossy reflections on the sunglasses, strong cinematic contrast, cool blue rim lighting from the planets, subtle warm highlights on the face, ultra-detailed 8k look, no text, no watermark, no helmet, no extra people.
