I'm entering this photography/essay contest but I can't think of anything to do with the essay. Any creative juices flowing out there?

OK so you’re supposed to pick 5 of the following things and take pictures of them:
1. Bird
2. Seed or pinecone
3. Spider or spiderweb
4. Bud on a tree branch
5. Something that looks like a letter of the alphabet
6. Detail of a snowflake
7. Animal tracks in the snow
8. Interesting icicle
9. Tree with no leaves
10. Plant peeking through the leaves
11. Interesting sand pattern
12. Seashell
13. Kelp or seaweed
14. Driftwood on the shore
15. Creature in a shell
16. Rock or sand pattern
17. Interesting rock or rock formation
18. Prickly cactus
19. Plant growing on a rock
20. Colorful sunset
And you’re supposed to write a 1000-character (I know, easy, right?) essay that finishes the sentence “I am inspired by nature when…”.
I just can’t think of what to write about. I’m worried that once I find something to write about, I’ll get going and it’ll be, like, 5000 characters.
