expression chart for a chart of expressions
expression chart, full body for a chart of expressions and a full body image
works particularly well with the high res fix, if you don't upscale, then a lot of the time the expression parts will be too low res.
Combines well with character loras.
Trained on a bunch of different types of expression charts, what you get is mostly gacha; the only control you have is in how many different expressions you include as tags, and if you use full body or not.
