Happy to help. Also, national treasures from around the world could also be a fun idea for a series of mini-series. Each mini-series focusing on one country or region

I'm just spitballing random ideas but maybe the planets and other notable celestial bodies(the sun, Earth's moon, Pluto) in our solar system, naked-eye galaxies, the seven wonders of the world, and/or cloud types. I don't know how well these will translate into oc adopts but they might be fun to try out

Unless you have arachnophobia, you could use some cool funky kinds of spiders(like mirror spiders and Florida crab spider for examples). Or just lesser known animals in general (mother nature loves making cool funky little fellas that can be used to make some neat character designs)

Glad to know that I'm not the only one Ping is acting fucked up for. Anyway, Miss Winter looks beautiful! If I had the extra money to get here, I would. Amazing work as always, Bambii!
