  Create stunning, ultra-detailed character art using this modular prompt system. This guide breaks down how to construct powerful prompts step-by-step for your text-to-image AI workflows.

• 🧱 1. Base Quality & Style

  Start your prompt with high-level artistic and technical attributes. These control the overall fidelity and mood of the image.

• Optional extras:

  (dynamic angle, dramatic shadows, depth of field, lens flare, ambient haze, 64k texture)

• 🧝 2. Main Character Description

  Describe your subject with appearance, outfit, and distinguishing features. This part determines the focus of the artwork.

  (full body of a youthful [character type], [hairstyle], [eye color], [skin type]), ([outfit], [accessories], [distinct features – wings, glowing eyes, tattoos, etc.])

  These terms help avoid common visual flaws or unwanted styles.

  Lower (6.5) = more adherence to the image model
