Example scenes (replace [DESCRIBE YOUR SCENE] with one of these):

1. The Valley of Flowers Beneath Two Moons: A rose-gold moon and a violet moon rise over a vast valley of glowing magenta and turquoise flowers, as a white crystal river winds toward floating mountains wrapped in soft pink mist.

2. The Sunken Palace: Rippling sunlight falls through deep turquoise water onto a sunken marble palace wrapped in coral, as small fish drift past its broken columns.

3. The Giant Mushroom Swamp: Soft teal light from glowing giant mushrooms reflects on a misty swamp at night, where a wooden boardwalk winds between twisted roots.

4. The World Tree Above the Cloud Sea: A colossal world tree with glowing cyan veins rises above a sea of peach and lavender sunrise clouds, as waterfalls of light pour from its branches and tiny cities shine along its roots.
