INPUTS TO COLLECT - subject: Character details — height,...
Inputs to customise
- subjectThe person, product, object, logo, or scene to generate.

- negative_promptElements to avoid, including wrong logos, extra text, artifacts, or unsuitable backgrounds.
Quality checks

- Hollow green eyes must be the sharpest and most luminous element in the frame
- Character must feel genuinely spectral and threatening, not cartoon-Halloween
