💡 Tips for Best Results

  • Clean Sketches: While the AI can handle rough outlines, cleaner sketches generally yield better results.
  • Specific Prompts: Be precise and descriptive, but try to limit your prompt to around 75 words for clarity.
  • Use the Image-to-Image Tool: Add an IMG2IMG tool to further refine and perfect your artwork.
