I don't like Hazbin but I feel people are ofter WAY too harsh on the character designs. They act like they are these horrendous unfixable things when I reality I just find them quite overloaded and animation unfriendly, but hey I feel like the show wouldn't be half as popular if the character's looks weren't so out there!
However I just LOVE what you did with Charlie here, in the original she is by far the most uninspired looking character and you made look so unique!
