Your art is great, but it isn't funny
The expressiveness of your animation, drawing style, and acting is spectacular. It's getting better and better. But it's lost the comedic flair your older work had. I don't know what it is, I just know it isn't there. Perhaps there's less passion in your writing now. Try something new. Something you haven't done before. Then come back to these comedic-style toons with a fresher mind.
