Not bad at all.
8/10.
The animation was quite good. You recycled some animation, but you reuse it so well it's easily looked over. Your voice acting could be better. I noticed you did a "silent yell" where you're inflecting your voice to show emotion without raising your volume. Get some good sound equipment and by all means yell.
So timing, a lil' more fast paced humor and take the acting up a notch and this would be a perfect 10 for me. You still get a 5/5 ;)
