I finally made a LoRA with Civitai's new trainer. If you want to use the checkpoint model, here's the link: https://civitai.com/models/162402?modelVersionId=184398

Negative prompt I recommend: fat, obese, long hair, (deformed iris, deformed pupils, semi-realistic, cgi, 3d, render, sketch, cartoon, drawing, anime:1.4), text, cropped, out of frame, worst quality, low quality, jpeg artifacts, ugly, duplicate, morbid, mutilated, extra fingers, mutated hands, poorly drawn hands, poorly drawn face, mutation, deformed, blurry, dehydrated, bad ???????, bad proportions, extra limbs, cloned face, disfigured, gross proportions, malformed limbs, missing arms, missing legs, extra arms, extra legs, fused fingers, too many fingers, long neck, BadDream, UnrealisticDream

You will need to also download BadDream & UnrealisticDream to get the full effect of the negative prompt.
