There's a lot of Toriel in the dataset, so I recommend that you put "toriel" in the negative prompt to avoid her features popping up.
This is what works best for me:
Positive
lines, cellshading, score_9, score_8_up, score_7_up, score_6_up, score_5_up, score_4_up, BREAK <lora:Cumbread_Style_Pony_XL_V2_r2:0.8>, cum8read, by cumbread
Negative
source_anime, source_pony, {patreon, text, logo, signature}, simple background, 3d:0.5
