Adding a tier for request (Patreon)

I'm adding a tier for people to request single images (1/month). I'm limiting the number of people in that tier to make sure I can keep up. If so, I might increase the amount of slots or add another tier for 2 request per month. Please try to keep the request relatively simple (AI has it's limitations).

No gore/furry/futa (I don't have judgement against these, just not for me). No Loli/shota.
