The slick trick is to get a head you like off an MMD, game rip, or uncommon booth and swap it onto one of the common booth bodies like Merino, Eyo, Wolferia, etc. It doesn't take too much work - just headswapping and color matching the body textures, and you'll be unique and original.
Lots of the uncommon booths especially have really cute faces and hairstyles, but nobody uses them because they don't have a gorillion outfits like the common ones do.
