I have seen hundreds of channels creating their fan art about this fabulous series, I am a 2d and 3d animator and I am creating art about ideas that I find fun. Where could I ask about permissions to create this art without disturbing our beloved DaFuqBoom!?

I really love his work and I don't want to be a bother to him since I adore his great effort and work, he is an example to follow as a quality animator. Thank you for taking your time to read this question.
