Horror style

Guess where I'll start... Using "furry, anthro," is optional... The focus is on a black-and-white atmosphere, so adding "black and white, monochrome," is recommended, but also optional. Otherwise, just use your imagination) Everything will work on an intuitive level... Need sharp fangs? Distortion? Long limbs? Just write it in. But at the same time, pay attention to the negative prompt so that it doesn't contradict the main one. You can also use prompts that completely kill the atmosphere in the image and make it unpleasant... something like "horror, grey atmosphere, grey fog," (that's the most basic, but you get the idea). Realism works, but the effect from it won't be very noticeable (depends on the situation). And I recommend adding "best quality, solo," at the beginning (the second one, if there is only one character in the image).

Negative prompts:

Be careful here, since the LoRA allows you to create distorted figures and images (to some extent). Mainly try to make sure that your main prompt and negative prompt don't conflict with each other. And here's an example of a basic negative prompt for an anthropomorphic character (or a regular one), where they look relatively normal but can be immersed in a gloomy atmosphere:

Watermark, Fused tail, bad eyes, lips, bad anatomy, bad had, fused fingers, fused face, bad face, bad quality, bad body, fused legs, bad details, particles, bad clothes, bad hair, fused body,

If you need to "break" the character and make them more "beaten" and grim, don't forget to also change the negative prompt (I know you already understand all this... I'm just saying this to be at ease).
