1. Middle Goth
2 Grey hoodie green socks
3.Bee girl
Those three require very little change and its and easy lay-up for most artists.
As far as the other two, the cotton-candy-colored demon girl needs a complete outfit revamp. It's an easy revamp as long are youre not married to the outfit, you would have to let it go,it needs to be changed. Also, loli body type would work better with the cotton candy theme. The black superhero would need different colors for her outfit. Possibly a new outfit in general. and for that, you're going to have to find an artist that does superhero outfits in general or, you would have to use AI like stable diffusion to come up with a more precise reference if you just want to use any artist
