Based on the visual novel "Cinders" which I played ages ago, remember it being fairly good. I did two versions, one is based on the regular art, the other I'll upload is based on the main menu and ending art with the purple theme.
Potentially Useful Tags For Both Versions: solo, upper body, (hips:1.5)
Potential Negatives For Both Versions: simple background, wall, stone wall, (height difference:1.5)
Trigger Word for the first version: cindstyle
Lora Weight: 1.1 with Hassaku and HornyFox, 1 with Pony Diffusion. Generally would suggest 0.9-1.2. Higher weight causes more detail to the point of becoming cluttered.
Trigger word for the second version: cindendstyle
Also Include: purple theme
Lora Weight: 1.2 with Hassaku, possibly 1.1 though the skin coloring starts becoming less accurate I think. Untested with other models.
Notes From Testing:
-Likes to generate certain backgrounds, like certain walls/structures. I put 'wall, stone wall' in negatives to try and combat this, still happens though.
-Might like generating a regular standing pose given the visual novel data, though can certainly do other poses if prompted right.
-Performs best with upper body images, hence my recommendation of the upper body and hips tags above. Haven't tested this, but potentially if you lower the weight it might help with full body images (obviously at the expense of losing some of the style but you might be able to find a happy medium).
-Multiple characters often can be sized weirdly (where those not in focus are tiny), that's why I suggest (height difference:1.5) as a potential solution although I'm not entirely sure it solves the issue. Seems to reduce it though. Otherwise, tags like 'solo' can obviously help avoid other characters appearing at all if they're unwanted.
