It depends. I’ve generated over ten thousand images and dozens of hours of video using AI, and the results generally come down to two things: how the LoRA was trained and the prompt itself.
I won’t dwell too much on the topic of LoRAs, but usually, the more realistic you want the AI-generated changes to be, the more the LoRA needs to alter the face as well. Most versions of "Enjoy Your Imagination" (versions 2–4 have already been deleted) were flawed because they preserved the face exactly as it was; this often resulted in a deformed body. The AI couldn't manage to keep the face unchanged while generating a nude body, leading to anatomically poor results.
If you want the face to remain as unchanged as possible, your prompt needs to match the framing of that face. For instance, if the source image is a high-angle shot but your prompt specifies a low-angle shot, the AI will have to completely rework the face, meaning it won't look the same anymore. But if you use a prompt like:
"Keep her head and hair exactly the same. Start with and Keep her head as a base for the rest of image. exatly the same view on her face like image source"
and the rest of your prompt doesn't conflict with it, you might get a face that is quite possibly identical pixel to pixel. The AI will simply keep the face as-is; it won't even try to "recreate" it, but will instead preserve that face from su It seems AI still isn't capable enough to effectively change the viewing angle of a face without altering it. Of course, as you wrote, the solution remains to train your own model.
And one more thing about lora for qwen. Try this one. In old thread someone pasted it with message like "every lora is making bad tits which looks like plastic and this one do it better" but The body generally looks better. I'm not sure about the face it's generally fine for me, but that might be my prompts rather than the LoRA.
But there is definitely one defect: the tip of the penis cannot be visible because its ugly

thats why i'm asking, maybe someone will find something better.
edit: oh, maybe one more tip. Try to find your seed. Keep changing seed until you will get face unchanged. Then save it and use it rather than standard seed. Somehow it works.
