Can I have your Hat?

So, Cheshire cat was meant to be only smiling but I observed it 3 years after I made this and it actually looks like if he was talking(the teeth are a bit separated), trying to persuade the Mad Hatter to lend him the hat, as he always does(movie). Anyways, I did get the looney expression.
Hope you like it. I used stippling (marking coloring with only dots-no lines).
