- Lighting: Warm golden-hour rim lighting with soft directional fill from screen left

- Environment/Scenery: Dense pine forest, soft ambient ground mist

[SUBJECT DIRECTION & ACTION]
|
|
The subject from <Picture 1> walks slowly through the path, glancing toward camera-left in awe. She turns slightly, speaking softly: "Look at the way the light hits the trees."
|
|
|
|
[AUDIO CUES]
|
|
Ambient forest breeze, soft footsteps on twigs, warm cinematic background strings.`
