This was an experiment on adding "anime" to the prompt. This is a before/after of emphasizing that keyword. Here, one can see cel shading and clear outlines.

One thing to note is that "anime" is not a tag on Danbooru, and yet works just as well. There is a Danbooru tag, "anime screencap", that works similarly, though that makes it look more dated and is thus not recommended unless explicitly wanted.

Made with NovelAI's UI.
