I found that realistic models can hardly generate good faces from side. So I trained a simple Lora to make it happen.
You may add control prompt such as "facing to the side", "facing up", "looking at the side", "looking down"...etc. to have better control of the direction.
"Looking at viewer" is not recommended, which may generate unexpected result.
nsfw is also not supported in this version, I may update to v2.0 to include it (when I got time).
