Finally there is a far more comprehensive list of what I am or am not comfortable doing. You can see my most common requests below, but for a full list, please head over here:

(No, I don't RP, but this is the closest thing I could find to an actual list, just assume this is for what I will draw)

Here are the genre's I excel at, and am more than willing to do
Sex (homosexual or heterosexual)
Pinups
Bondage
Stuck
Sitting/pinning
Suspension (Ropes/leather only, no hooks)
Hypnotism
Mild breath play
Mild size difference
Mild musk
Oral sex
Scruffing/biting
Werewolves
Unwilling Vore
Goo/blob Vore
Plant Vore
Paws
Tying
Leather gear <3
Quicksand
Sheathplay
Underwear
Cuddling
Biting
Coiling
Chastity
Cuckholding (Newly experimenting)
(and any mixing of the above genres)

Here are the genre's I will NOT do, and I am uncomfortable drawing*
-Watersports/scat
-Gas/smell/extreme scent play
-Gore
-Cutting/crushing/pain play
-Ferals/Bestiality**
-Babyfur/Pedophilia/Diaper play***
-Incest
-Snuff
-Rape (Roleplaying is fine, but no non-consensual sex)
-Genitalia/Soul/Anal Vore
-Genitalia absorption/fusion
-Hard Vore/Digestion
-Micro>Macro vore (In short: predators just need to be bigger than prey)
-Hyper (abnormally large/exaggerated appendages)
-MLP, Lion King, Sonic, etc. (Children-show/movie characters in adult situations)

*I reserve the right to refuse any commission/genre, even if it is not currently listed here
**Vore with ferals is fine, but I will not be putting any 4-legged creatures into sexual situations.
***ALL characters MUST be of legal, consenting age.

Finally, here are a few genres I'm certainly willing to do, but I should warn you they are not my forte
-Humans
-Transformation*
-Consensual vore
-Latex/Rubber/Balloons
-Micro Vore

*I can certainly do transformations, like for werewolves, but I'm not really good at making it sexy

TOS summary for commissions:
I use Square invoices to charge for my commissions.
I charge full price up front unless otherwise agreed upon.
Partial refunds are possible based upon the amount of work done. If 50% of the commission is completed, you may be refunded up to 50% of the cost.
Complexity fees may apply for complex clothing, complex markings, complex ornaments, complex anatomy, etc.
Changes to the commission may incur additional fees, depending on circumstance. If you'd like a character in a new position when we've already drawn lines for example, this will require an additional fee.

If you have any questions, feel free to comment below or send me a note. I understand there are some gray areas in sexual content, and I am more than happy to discuss them. If you would like me to explain or clarify ANYTHING, or to ask if I’m comfortable with your particular idea, ask away, I won’t bite your head off for bringing something to the table that you’d like to inquire about, even if it’s on my no list, I’m willing to speak to you about it.
