So I'll just come to terms and say that I fucking LOVED this. There were a few hiccups here and there, but not with any animation or artwork. It just has to do with humor. Yes, I know that the whole point of the Stamper sketch was supposed to be that it seemed like he was nothing but a hopeless perverted son-of-a-bitch who just couldn't learn to shut up. But even then, that was dragged out for a little bit past my limit for how long I could take it.
You have to understand, when it comes to shortish animations like this, you need to pace your punches. If it is only thirty seconds to one minute, you need to deliver them pretty frequently. When it's about ten minutes long, then you can take a little bit. Your animation was just about inbetween the times. So you seemed to drag it out too long. But only for one sketch, so I can't really complain much.
I can't wait for the next episode, in short. Your mascot is a very well-designed mascot, well suited to your style of animation (yes, I have seen some of the others). I'm just glad that you also have the great voice talent to go along with it.
