Generally:
Sketch $7
Lines $15
Add color to sketch or lines +$3
Full Color/Shading $25
Extra character +75% of option (so two character lined work, $12 + $9)

If your idea is complex it may cost more than these baseline prices.

I will not do any nsfw stuff as of right now besides male/female nipples.
I will not do any scat/ws/diaper/cub stuff.
Any fat, inflation, blueberry, etc. idea I will probably do. Drawing slob, farts, sweat, etc. is also something I will do!

I also like drawing unorthodox characters. Like if you wanna fatten up a robot somehow.

I have the right to refuse your commission, but I am super open the the vast majority of ideas, so don't let that deter you.

I require payment after you approve the sketch. You can pay before then if you want to, also. Accepting Paypal and now Google Pay!
If you're getting only a sketch, you must pay up front.
Feel free to ask about an idea and its cost if you're not sure about price or if you're not sure I would be willing to do it.
