Eyes — colour and pupil shape
Specify a pupil shape — does it draw it?
Eyes occupy very little of the frame and receive the most attention in anime rendering, which is why fine detail sticks.
Every cut below shares one seed, one base prompt and one sampler setting, and differs only by the tag marked in amber.
What each cut shows
heterochromia- The two eyes come out different colours — though which eye gets which is not yours to choose.
glowing pupils- The pupils emit light and bleed into the surrounding area — with a side effect of darkening the whole scene.
star shaped pupils- Star pupils, exactly as named — a cartoon convention reproduced verbatim.
heart shaped pupils- Heart pupils, as accurate as the stars.

Takeaway
Symbolic shapes land better than realistic ones, because the training data holds an unambiguous icon for them.
How far this result reaches
glowing_pupils moves the lighting as well; it will fight anything asking for a bright scene.
Measured on a single Stable Diffusion family checkpoint. The same tags can behave differently on NovelAI, Midjourney or another checkpoint. This is a reference point, not a verdict.
