Current Commission sheet, with examples, pricing details, and options.

Clarifications. Anything showing variable pricing is based entirely on complexity. If your (additional) characters have intricate patterns, accessories, etc., then those are going to cost more.

NSFW / Mature content is based on level of difficulty again. Certain things are simply more time consuming. I will also require some for of valid verification you are 18 or older before accepting.

As for the additional character limit, there are two restricting factors.
First clarification is that the line indicates 3 characters in addition tot he base one, so a total of 4 in a single image. This is mostly due to file sizes and not wanting to brick my tablet keeping up with a 20,000 by 20,000 pixel monstrosity. XD
Second, this wouldn't apply to something like a comic, or sticker sets. I haven't experimented with comic formats yet, as of writing this, but a multitude of characters over several pages would obviously be feasible. I just might want to remain aware of how many or on the page at the same time.

If there are any other questions, please comment and ask, and I will do my best to clarify. Thank you.
