You can experiment with negative prompts, but for me ‘rz-neg-foranalogportrait’ give very good results.

I recommend these parameters:

LoCon Strength: 0.5
Size: 768 x 768 - Truly I have not tried with other resolutions; I think the most stable is this measure.
CFG: 7 - 9.5 is perfect (in my opinion)
Sampling Steps: 20
Sampling Method: DPM++ SDE Karras works very well for portraits.
