V1: Should do elves and any other girls just fine. Makes them cuter and gives them what I consider to be a perfect body type with smooth skin and a slightly toony look. There may be problems with the hands, I'm working on it for v2.
Use it at any strength you want within reason, I have found it works well up to 1.6.

Secret bonus: Try "twi'lek"

Trigger word is em_g1rl.

Optional prompts that work well to shape physical attributes are: thick thighs, thigh gap, curvy

I highly recommend using these quality prompts:
POS: masterpiece, high quality, highres, high detail, newest,

NEG: worst quality, low quality, lowres, blurry, watermark, bad anatomy, bad hands, deformed, toned, skinny,

V2: More variety, cleaner backgrounds.

V3: even cleaner backgrounds, more consistent morphology and prompt adherence. Cleaned up eyes and nipples, they should be cisp now, along with slightly better hands.
