The Antidote to "Twee"
I really like this; the bear's morose reaction to unfettered zany enthusiasm is pretty much exactly how I feel when I turn on the television too early on a Saturday morning and find myself confronted with children's show presenters.
The facial expressions are great; I especially like the bear's look of puzzlement in the third panel, and his gruff gloominess at the end. And I actually think you could stick with the blue pencil look for future comics; it fits the tone of the concept perfectly.
