Eh...
It's a good drawing, but it's not a good rendition of The Joker.
I suppose it's alri.ght, considering you based it off of Heath Ledger's version and not the "true" version.
As a drawing unassociated with The Joker, I'd give it a 8-9 but as a drawing that's supposed to adapt The Joker as a female, it's around 1-4
