2. Swimming Pool 2 (Forest)
This isn't about a pool, but it's the only one, so I thought I should put it in this section, as it still was part of the description lesson.
Rough and ridged, the bark of the oak scraped against my knees with a sharp pain. The dappled sunlight cast emerald light far below me onto the leaf-coated ground. A gust of wind and I clung to my spindly branch as rustling filled my ears. Suddenly, the metallic tang of blood flooded through my mouth and I realised I had bitten my lip. Inhaling the distinct fragrance of the forest I reached for the next branch.
