Who thinks that I should draw an evolved form of Arcanine?

I sort of have an idea for the evolved form, but this is my opinion, so please don't hate.

Appearence: A large black dog pokemon with silver stripes. Dark grey colored fur fluffs (That's what I call them.), and red eyes. It also has 3 white tails. What do you think? I have yet to think of the shiny coloration, so you may help out with that.
