If you are using it with another LoRA (on character) I recommend to decrease weights of character's LoRA and increase LoRA's style.

Also don't forget about tools that can improve your arts: highres fix with ultrasharp, animesharp, fatal-anime-50000G, lollypop, and tools like dddetailer, SD upscale, controlnet, Photopea, inpaint, etc.
