Yeah, in my personal experience, when relaying only in promps the generated image is often to have errors. I like to use a combitantion of control-net or Also Krita AI diffusion. (wich i love, that is god for me,ok more or less, at least is better that just prompting.)
Idk if you are asking to create art for games. But some other tools i like to play with are background removal tool named 'RMBG-2-Studio' and 'FaceFusion'' using te 'face manipulation' module. Those tools can be easily installed with pinokio (i never used this one, i just know it's there).
