The Anatomy of a Perfect Prompt
Every effective prompt follows a clear structure

Examples: a cat, a futuristic city, a woman in a red dress
💡 Always start with the subject. Be specific about what it is.
Style
The artistic style or visual aesthetic
Examples: photorealistic, anime style, oil painting, 3D render
💡 Define the style early for consistent results.
Details
Specific characteristics, colors, and features
Examples: golden hour lighting, cinematic composition, vibrant colors
💡 Add 2-3 key details that enhance the main subject.
Technical
Resolution, format, and quality specifications
Examples: 8K resolution, 4K, high detail, sharp focus
💡 Include resolution for higher quality output.

Common Prompt Mistakes to Avoid
Vague Prompts
❌ Bad Example:
"a picture of a dog"
✅ Good Example:
"a golden retriever puppy sitting in a sunny park, grass field background, photorealistic, natural lighting"
💡 Specific details help the AI understand exactly what you want.
Too Many Keywords
❌ Bad Example:
"a cat dog bird fish tree mountain sun moon stars sky cloud rain snow beautiful amazing stunning incredible 8K 4K HD realistic unreal engine octane render watercolor oil painting digital art anime manga cartoon"
✅ Good Example:
"A majestic lion walking through the savanna at golden hour, photorealistic wildlife photography, cinematic lighting, 8K resolution"
💡 Focus on key elements rather than keyword stuffing. 15-30 well-chosen words work better than 100+ random keywords.
Contradictory Instructions
❌ Bad Example:
"a realistic photograph drawn as a cartoon anime style oil painting"
✅ Good Example:
"a portrait in anime style with vibrant colors and clean lines"
💡 Choose one clear style. Mixing contradictory styles confuses the AI.
