yeah that kind of pic with multiple characters is extremely difficult, it is a skill issue but a reasonable one. ai art is completely iterative and nothing is ever done done.
personally i like solo transparent background because the character can be photoshopped into other stuff later and then that image used as controlnet or inpainted to actually achieve the image you want.
like for me to do what you just posted i would preferably generate a generic image with three bodies, then generate 3 separate heads, then photoshop those heads onto the bodies and run that image back through to blend it rather than trying to oneshot it
