Tested on:

Sampler: DPM++ 2M SDE

Steps 30 -50 (higher will have better results)

CFG scale: 6

Size: 896x1152

Model: illustrij_v11Updated (use this checkpoint for getting a closer result)

trained from in-game screenshot + some random picture from videos

Only one clothes styles, might want to add more when I got bored :^)

full on 1024 * 1024, it should have better result default. But hires.fix will helps a lots of blurry eyes.

character will sometimes have anime look it is hard to trained 2.5D style character on a more anime checkpoint, but the result should be very reasonable.

The character also some time have a frame around, I kinda like it, it is what in games have.

Face and the style should be very close.

All background and clothes has been tagged using NLP, but it is still has default looks, and kind of hard to change with less prompt.
if you want the in-game looks, a simple prompt works just fine.
