Try size: 512 x 768 or 597 x 896 (flux: 768 x 1024 or above requires more sampling steps) / 768 x 1024 (pony)
Weights: 1.0 (flux) / 0.9 (pony)
Note: Occasionally, if the sampling steps is too low, limbs may become distorted or blurred, but strengthening the description can improve it. I'm not good at using natural English language on Flex Dev. If you think your expression is better, you can describe it in your own way. The training materials do not use real faces. The face, bodies and clothes are all redrawn by AI on PhotoDirector APP, and more than 50% of them are MajicMix pictures, and the other are Internet pictures or video screenshot. Also, thank you very much for reminding me of spelling errors in prompt. For example, rabbit is spelled as ribbit...😅 (flux)
Note: Basically it is low-end version, but nsfw is easier than flux. (pony)
