I like your listing, Sierra.
I see a broad category of "natural wonder" which could be considered in the "landscape" category. I'm thinking waterfalls, mountains, trees, outer space to go with the floral, fauna, and animals.
Also "architecture" as manmade wonder--skyscrapers, houses, electric lines, paired in the building category.
Let's not forget "geometric" shapes --circles, triangles, squares, et al.
