      - prompt: m@n, A young man with a medium tan, golden undertoned skin and short,
          tightly curled hair. His clean jawline carries a faint stubble, adding sharpness
          to his look. Wearing bold brown glasses, he tilts his head slightly forward
          and to the side, eyes meeting the lens with a calm intensity. The soft circular
          light behind him frames his confident yet effortless pose.
      - prompt: m@n, A young man with fair skin and a cool undertone, his gaze steady
          and self-assured. His hair is styled in a casual, tousled cut with natural
          volume, slightly messy yet effortlessly put together. Wearing a fitted navy
          crewneck tee, he stands against a plain light background, exuding a clean,
          modern aesthetic that blends ease with quiet confidence.
      - prompt: m@n, A young man with fair skin and short, tousled brown hair styled
          with a natural fringe. He wears bold, rectangular black sunglasses that
          add sharpness to his look. Dressed in a simple white crewneck tee, he gazes
          off to the side, his expression calm yet slightly intense. The outdoor light
          casts soft shadows, enhancing the modern, minimal vibe of the portrait.
      - prompt: m@n, A young man with a fair skin tone and tousled blond curls, styled
          casually for a natural look. He wears matte yellow round sunglasses with

          contrasts sharply against the light background, making his features and
