Inputs to customise

  • subjectThe person, product, object, logo, or scene to generate.
  • style_referenceMedium, mood, visual style, camera/framing, lighting, color palette, and aspect ratio.
  • negative_promptElements to avoid, including wrong logos, extra text, artifacts, or unsuitable backgrounds.

Quality checks

  • The logo glow effect is described with specific hex colors (blue #00A3FF to purple #9B00FF) and both inner halo and outer bloom dimensions — not a generic 'glowing outline'.
  • The WOW emoji transformation is described as a specific 3D render with photorealistic sphere, open O-mouth expression, and Cinema 4D-quality shading — not 'make it look real'.
  • The text transformation specifies Poppins ExtraBold weight 800 with a specific drop shadow definition — ensuring the model targets the correct font weight and styling.
