I'm sorry this will be harsh, but bear with me
I understand you did this with good intent, and I don't blame you. It's a good comic. However, Vasquez, like other artists would not like his work bastardized or emulated in a less-than-professional fashion. Even if it were professional, there would still be issues. Though thought does count, and imitation is a high form of flattery, Nny is Vasquez' not yours. Leave him be, and leave your flattery to words, not a flash cartoon.
Nny's purpose for existing was to serve as an outlet for Jhonen's artistic talent, and maybe make him some coins. He wasn't created to be plastered on shirts, or pushed into the realm of other people using his image for any reason.
I'm sorry, but this zero is to tell you what shouldn't be done
