About the orga tag
orga is an artist tag that NovelAI Diffusion can use. On Danbooru it has 140 posts, and its best-rated still image scores 50. The samples above put the tag at the front of a fixed base prompt with seed 1234, so the differences between tags come from the tag alone.

How these samples were made
Every image uses 832×1216, seed 1234, 23 steps and the k_euler_ancestral sampler. The base prompt and negative prompt stay the same for every tag, and only the tag under test changes. Images flagged by the NSFW check are regenerated with a new seed or hidden.
From the Danbooru wiki
Orga is an artist tag associated with mostly Ghibli uploads to Danbooru from April to November of 2007 by ShinjiDude
It's unclear which account (Pixiv or otherwise) this artist alias may have been associated with.
Later artists would also come to use the name, generating subsequent confusion:
organ derwald orga_(orgacl) yomoyama874
Eventually a longer name (perhaps a parenthesis for emphasis) could be useful here, as well as any external sites the artist may have used in the early 2000s.
