Urban Alley Night Portrait with Motion Blur

Ultra-realistic cinematic night portrait, standing in a {argument name="location" default="dark urban alley or industrial concrete street"}. The subject is wearing a {argument name="outfit" default="glossy black leather bomber jacket and loose oversized white trousers with white sneakers"}. Hands casually in pockets, body slightly turned, face looking sideways (profile view) with a calm, mysterious expression.
Lighting is deep blue cinematic low-key lighting, high contrast shadows, with a strong cold blue color grade dominating the entire scene. A soft directional light hits the face from the side, creating sharp highlights and deep shadows.
Add a motion-blurred {argument name="blur element" default="human silhouette"} passing beside the subject (left side), captured with long exposure effect, creating streaked blur while the main subject remains perfectly sharp and in focus. Background is a dark, empty concrete wall or alley with minimal texture, slightly out of focus. Atmosphere is moody, mysterious, luxury editorial style.
Shot on 50mm lens, shallow depth of field, ultra-detailed skin texture
