## Negative Concepts

To avoid unwanted elements, describe what you want clearly:

Instead of: "no text"
Use: "clean image without text, pure visual"

Instead of: "no people"
Use: "empty scene, unpopulated environment"

Instead of: "not blurry"
Use: "sharp focus, crisp details, high clarity"

## Batch Generation Tips

When generating multiple variations:

1. **Keep core prompt consistent** - Same subject and style
2. **Vary specific details** - Colors, poses, backgrounds
3. **Use numbered batches** - Track which prompts work best
4. **Iterate on winners** - Refine prompts that produce good results

**Example batch workflow:**
```bash
# Round 1: Explore styles
"pixel art robot, 8-bit style, blue colors"
"pixel art robot, retro game style, warm colors"
"pixel art robot, modern pixel art, neon colors"

# Round 2: Refine best style
"pixel art robot, 8-bit style, blue and silver colors, friendly expression"
"pixel art robot, 8-bit style, blue and gold colors, heroic pose"
```
