Moody Gym Bathroom Mirror Selfie.

"A realistic mirror selfie of a young man standing in a dimly lit modern restroom or gym locker area, holding a black smartphone with a multi-lens camera up in front of his face with one hand while giving a thumbs-up with the other, looking down at the screen with a cool, focused, slightly serious expression. He has short, dark, thick, curly, tousled hair with a loose fringe and large black round-rectangular framed glasses. He wears a faded charcoal-grey oversized crewneck sweatshirt with a faint chest print and a black undershirt collar peeking out, loose black drawstring trousers, a thin silver chain necklace, a black athletic wrist band on one wrist, and a stack of black and silver studded bracelets on the other. A black backpack hangs over one shoulder. Behind him are plain taupe-grey walls and white tiled surfaces with a urinal and chrome fixtures softly visible on the right. Moody, low-key indoor lighting with soft overhead light, natural skin texture, slight phone-camera grain, candid Gen-Z gym-selfie aesthetic, 3:4 portrait aspect ratio, a muted color grade of charcoal grey, black, and warm taupe tones."
