Compared with my Tour (Jewelpet) model, I simplified the prompts during training, so background colors, open mouths, or open eyes are not required. Unfortunately, although I also trained several shiny purrloins, it seems useless even though you tag 'shiny'. I suggest inputting style prompts like 2D art fanart, Pokémon anime style, pixel art, or at least pastel colors, cel shading, thick outlines, and so on, as most of the training data contains related descriptions.
