Generally, it would be good to have the same character with different face impressions and different outfits, eg, a prince in formal dress, or in a battle uniforms. You could provide separated body image/ postures / costumes with head images of different facial impressions, so the users could freely combine head to body for different needs, and that opens up a lot of freedom to create. Currently, all AI generated characters are kind of 1 shot for all, 1 static image of fixed head / outfit / posture and that is it, not much room to play around.
