### Full prompt
```text
High-contrast digital portrait of a young man looking slightly upward with a determined, thoughtful expression. The face is rendered in realistic grayscale with sharp facial features, detailed skin texture, short dark hair, and light stubble. Dramatic cinematic lighting with deep shadows emphasizes his facial contours and jawline. The background is vertically split into bold abstract brush textures with vibrant [red] on one side and bright [yellow] on the other, creating a modern poster aesthetic. Painterly gritty strokes, centered composition, editorial art style, minimal clothing visible, dramatic contrast.
