Best Practices

Character Consistency

1. Establish core features first: Define key identifying features (shape, color, props) that remain constant across all views
2. Maintain proportions: Keep body proportions consistent between views
3. Color consistency: Use exact color values across all panels
4. Personality alignment: Ensure all emotion poses reflect the character's core personality

Art Style Guidelines

For Product Mascots:

• Flat vector: Best for logos, icons, simple brand characters

  • No gradients, solid colors only
  • Bold outlines (3-5px)
  • Geometric, simplified shapes

• Cel-shaded: Good for playful, cartoon characters

  • Limited shading (2-3 tones per color)
  • Bold outlines
  • Some depth without complexity

• Illustrated: For detailed, personality-rich characters

  • Textures and subtle shading allowed
  • More anatomical detail
  • Character depth and dimension

Emotion Pose Tips

• Make poses distinct: Each emotion should be immediately recognizable from silhouette alone
• Use props meaningfully: If character holds objects, vary how they interact with them
• Exaggerate expressions: Especially for small-scale usage (icons, avatars)
• Consider brand context:
  • B2B/Professional: Subtle, friendly expressions
  • B2C/Playful: More animated, energetic poses

Troubleshooting

API Quota Issues

If you encounter quota exhaustion errors, the skill automatically provides your optimized prompt. Simply:

1. Copy the prompt from the error message
2. Visit gemini.google.com
3. Paste and generate
4. The web interface has a separate quota from the API

See the gemini-imagegen Troubleshooting section for more details.

Character Consistency Issues

If views don't match:

• Use the multi_turn_chat.py script for iterative refinement
• Establish the isometric view first, then generate other views referencing it
• Be more specific about distinctive features (colors, shapes, props)

Layout Problems

If the layout doesn't match the specification:

• Add more explicit layout instructions
• Specify panel sizes in percentages
• Use terms like "magazine layout", "reference sheet", "character turnaround"
• Try the pro model (gemini-3-pro-image-preview) for better instruction following
