## Scene Composition Guidelines

### Common Children's Book Scenes

**Opening/Introduction:**
- Character in their home environment
- Establishing the normal world
- Cozy, safe feeling

**The Problem/Adventure Begins:**
- Something changes or goes wrong
- Character shows concern or curiosity
- Tension in the composition

**Journey/Middle Scenes:**
- Character in new environments
- Meeting other characters
- Action and movement

**Climax:**
- Dramatic moment
- Character facing challenge
- Strong emotions

**Resolution/Happy Ending:**
- Problem solved
- Joy and satisfaction

### Composition Tips

**Rule of Thirds:**
Place characters at intersection points for visual interest.

**Leading Lines:**
Use paths, branches, or objects to guide the eye to the character.

**Emotional Space:**
Leave room around characters for emotional breathing room.

**Scale and Perspective:**
Show size relationships - make children's world feel appropriately scaled.

**Page Layout Consideration:**
Remember where text will go - leave space for words.

## Maintaining Character Consistency

### Midjourney Character Reference (--cref)

Once you have a character reference image you like:

```
[scene description with character], [art style] --cref [URL of character reference image] --cw 100
```

**Parameters:**
- `--cref [URL]` - Reference image for character
- `--cw 0-100` - Character weight (100 = maximum consistency)

**Example:**
```
Oliver the gray bunny in red sweater exploring a sunny meadow with butterflies, soft watercolor children's book illustration --cref https://example.com/oliver-reference.png --cw 100
```

### Consistency Without --cref

If your AI tool doesn't support character references, use detailed consistent descriptions:

1. **Create a Character Sheet Prompt:**
```
Character reference sheet for [character name], [full detailed description], multiple poses and expressions, turnaround view, consistent design, children's book illustration style, [art medium]
```

2. **Copy exact description for each scene:**
Keep the character description identical word-for-word in every prompt.

3. **Use the same style keywords:**
Always include the same art style descriptors.

4. **Reference pose libraries:**
"standing," "sitting," "running," "looking up," "waving"
