Oh. My. God. It's perfect. It's really awesome! The dancing Zoidbergs on the N and the 5 are hilarious, I love it. And he's actually blinking!
I like that the whole cast of the show is on there because honestly the whole show is great, Zoidberg is just the greatest of the greatest. And yet they don't take away from him in the signature as he's the center and in the foreground. How you layered Zoidberg, the text and the others is really clever. Also, I don't mind at all that he's in the way of the A. I kinda dislike all these sterile and clean designs that are on vogue nowadays. Sure, they're elegant and can look nice, but they lack personality, imho.
You should actually take commissions and get paid to create these. (I can say that now after I got mine for free.)
Also, how should I credit you? So far I just copied Molang and put your name beneath it, with your name also being a link to your profile (even though you don't see that because of this genius forum design).
Tl;dr: I like it.
