I made this one day and for its amount of training data it's actually pretty good imo.
I highly recommend using this positive as a starting point.
Strength should be between 0.2-0.4
(masterpiece, best quality, high quality, highres, ultra-detailed)easynegative, (worst quality, low quality, normal quality), lowres, bad anatomy, nude, nsfw, blurry,I recommend generating on 512x640 image and then do highres fix
Works well with most anime/semirealistic models that i have tested
some good settings are
DPM++2M K 20+ steps cfg=4-8 (fast)
DDIM 25+ steps cfg=5-10 (balanced)
DPM SDE K 30+ steps cfg 4-6 (detailed)
