>>26876561There are two things, the highlights are a bit too harsh and she has dynamic shadows/lighting enabled on her model.
Most other VTubers have completely unshaded models (maybe with faux shadows), that are tinted by the environment light.
What she's doing usually doesn't look that great for anime models. Also the model doesn't cast shadows or reflections onto the stage, that ground it to that environment.
Her movements are fun as always though
