If using LoRA, it might be best to use LoRA "DMD2" in conjunction with it, setting the sampling step to around 10 and the CFG scale to 1.1-1.5 to generate samples (other detailed settings can be left at their defaults).
Adding the artist name to the prompt might also be effective, but this will need to be experimented with yourself.
Also, using LoRA related to "Numbers Suit" is effective for recreating the costume.
