Cyberpunk-Filmlighting für Cosplay-Fotos

Using the provided reference photo, transform the casual snapshot into a cinematic movie poster edit in a [Blade Runner-inspired cyberpunk] style. Retain the exact subject, pose, outfit, helmet, foreground composition, and convention center setting. Dramatically relight and color grade the scene: darken and softly defocus the background, deepen shadows, and introduce high contrast with cool blue-gray tones, subtle vignetting, and a soft film grain texture. Add a warm amber reflection and glow onto the helmet visor from ambient neon light while preserving realistic skin texture and photographic fidelity. Do not alter the character design or add text.
