It'll be 2-3 tokens per color-in, depending on complexity, No lineart edits will be allowed though, sorry. (Except for very small things, like a necklace with a pendant or an earring. A scarf or bandanna, however, would be an example of something not allowed.)
Anyways, based roughly off a pic I took of my own adorable dog (it's crappy, but she didn't seem to like the flash so I turned it off).
