just like KnockPainter have mentioned i think you should work more on facial expressions and also mouth animations ( i have tried a few times to make animation and i still fuck up mouth and walking cycles =D ) but other than that it's good , some jokes are stupid and some have made me laugh - at the ending that is damn good . i know this is gonna sound offensive but - try to make your own show , or animation - that way you can give it your own spirit , you know ? just saying x)
