Phone snapshot to cyberpunk movie poster AI Image Prompt

Using the provided reference image, transform the ordinary phone snapshot into a cinematic cyberpunk movie-poster style edit. Keep the same subject, pose, outfit, helmet, foreground composition, and convention-center setting intact, but dramatically relight and color grade the scene with a dark, moody Blade Runner-inspired cyberpunk atmosphere. Make the background darker and slightly defocused, deepen shadows, add high contrast, cool blue-gray tones, subtle vignette, and a soft filmic texture. Add a small warm amber reflection/glow on the helmet visor area as if from neon or sunset light, while preserving realistic skin texture and photographic detail. Do not change the character design or add text; make it look like a professionally retouched cinematic poster frame rather than a casual outdoor snapshot.
