Why Prompt Quality Matters for AI Illustrations
The quality of your prompt directly affects the quality of your AI-generated illustrations. Vague prompts like "a dragon" produce generic results, while detailed prompts with style, lighting, composition, and mood specifications create professional, publication-ready illustrations.
Based on Gemini 3 Pro Image best practices, effective prompts should include:
- Specific subject description - What exactly should appear in the illustration
- Art style - Realistic, fantasy, cartoon, watercolor, etc.
- Lighting - Natural, dramatic, golden hour, etc.
- Composition - Balanced, cinematic, rule of thirds, etc.
- Mood - Happy, mysterious, peaceful, epic, etc.
- Age-appropriate details - Adjustments for target audience
Our AI-powered prompt helper automatically determines all these elements based on your simple input, ensuring your prompts are optimized for the best possible results from AI image generation models.
Example: Vague Prompt
"a dragon in a forest"
Result: Generic, inconsistent style, unclear mood or composition
Example: Polished Prompt
"A majestic dragon in an enchanted forest, fantasy style, digital illustration, golden hour lighting, cinematic composition, epic mood, sophisticated, detailed illustration."
Result: Professional, consistent, publication-ready illustration with clear style and mood
Best Practices for AI Illustration Prompts
- Start specific: Include the main subject clearly (e.g., "a young wizard reading a spellbook" not just "a wizard")
- Specify style: Choose an art style that matches your book's genre and target audience
- Control lighting: Lighting sets the mood - dramatic for action scenes, soft for peaceful moments
- Consider composition: Rule of thirds for dynamic scenes, centered for symmetrical subjects
- Match mood to content: Ensure the mood aligns with your story's tone
- Age-appropriate: Adjust detail level and complexity based on your target age group
- Be concise but descriptive: Include key details without overloading the prompt
