I Don't Even Know (Patreon)

     I have no idea who these characters are. I don't remember if they were characters the commissioner had created, or if they're established characters he just liked.  (No offense to the commissioner; I just do too many commissions to keep track of, and I'm not familiar with many adult comic characters.) Does anyone recognize them? And did I get the likenesses anywhere close to right? They're not like my designs, so I'm assuming I had reference.
