Initial test: Got bored on Civit web and have some buzz credit there I would rather waste on myself. Results were helpful, so I figured why not share?
Trained on the 25x portrait images. Default Krea2 settings—nothing fancy or custom tune.
Trigger is not necessary but may boost by adding this to a new line: solo
Cons: tend to add black spots or moles, but just for short prompts. Also, being piercing-friendly, higher resolution may reduce inconsistency in intermediate quality (didn't test with wide sizes).
Pros: can improve some realism approaches & offers a different aesthetic take, such as a better understanding of nationality or race in some cases. Check those previews I had included.
Disclaimer: Any resemblance to a real person is purely a coincidental result.
