Great idea and artwork!
Please veiled616 can you ask Guroccubus to pose for:
吐血 spit blood
包帯男 mummy (have fun with bandages :-) )
生き埋め buried alive
チアノーゼ cyanosis (bluish face - asphyx)
顔騎 or 顔面騎乗 face sitting (asphyx)
痙攣 convulsions (shake yourself)
人質 hostage (e.g. someone holding a gun at your head)
凍死 freeze to death

and one posing turning yourself into a sex doll:
人形化 turned into doll

变态 metamorphosis

have fun!
