I may as well just put my character description here, so I only have to write this once and I can point my commissionned artists here.

Fireball is a ferret. I think he has the coat style called "cinnamon" but I'm not 100% sure on that (contradicting sources of information), but you can just look at other pieces of artwork to see what kind of colours to use. Like myself, he often changes his hairstyle and so doesn't have one fixed appearance (I will probably specify what kind of hairstyle I want for a particular piece).

He has a "tattoo" of a fireball on his left forearm. It's not really a tattoo like humans would get though, because fur covers his skin and you wouldn't see it. Instead it's just dyed into the fur. Fur grows out though, and this needs to be constantly touched up and redone. As such, you need not draw this fireball in the same style as any other piece you see (and I in fact encourage you to draw it in your own style, however you feel like).

I think that's all there is to it. I feel like I ought to write more here but I can't think of anything else to put.
