Would this make a good addition to my sleeve I started?

So far I have done a couple pieces of my sleeve shown below: apologies for the first one being in the wrap still I haven't taken a photo since it came off.

I'm struggling to decide what I want to add next and I was thinking of doing the Cheshire cat on my inner bicep area (so the opposite to the wolf) I found these photos(below) they would be altered of course and made to match better using the style I have already.

As this is the live action version of Cheshire I would use the blue highlights where they usually would go on him.

What do you guys think of the idea? I want to make sure that everything I pick fits well together at the end.
