I do wish I liked this show more, but I just can't stand Billy as a character. He utterly ruins it for me. If it was the /Grimm/ and Mandy show, well. Then I might watch it more. Lovely drawing, by the way.
I feel like Billy's nose needs to be 100x his body mass and Mandy is soooo cute~ I love how cute she is and this is what she would look like in real life. One of those cute but deadly little kids. Like Suzy from Phineas and Ferb XD
