Overview

This skill generates comprehensive character reference sheets with a specific layout optimized for product mascots and brand characters:

• Left Panel (40% width, full height): Large isometric view (3/4 angle) as the main showcase
• Right Top Row (60% width): Front, back, and side orthographic views

• Typography: Libre Baskerville font for professional label presentation
• Integration: Uses gemini-imagegen skill with quota fallback support

Perfect for brand guidelines, design documentation, animation references, and maintaining character consistency across marketing materials.

Quick Start

Basic Usage

To generate a mascot character sheet, provide:

1. Character description (what they are, personality)
2. Art style (flat vector, 3D, illustrated, etc.)
3. Color palette (brand colors)
4. Product context (what product/brand they represent)

Example request:

"Create a character sheet for a friendly penguin mascot for our ice cream brand. Flat vector style, blue and white colors with pink accents."

The skill will generate an optimized prompt following the standard layout format.

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
