Classic intellectual black and white portrait in city alley AI Image Prompt

A vertical black and white candid portrait of a charming young man with wavy, medium-length hair and stylish round-rimmed glasses, smiling warmly at the camera. He is wearing a textured, dark knit crewneck sweater, dark pants, and has a leather messenger bag slung over his shoulder with his hands casually resting in his pockets. He is leaning back against a rustic, detailed brick wall in a narrow, out-of-focus city alleyway, creating a classic, intellectual, and timeless aesthetic with rich film grain texture.
