Great job man! I really love how disturbing you make your characters look. Aang especially looks incredible in this. The voice acting is also really good.
There are a couple things that stuck out to me though, one of which was the initial composition on Zuko. There's a bit too much negative space behind him. When a character is looking in a particular direction, it's always better to give them room in the direction they're looking.
A line that didn't really make sense to me was, "I just wanna take you in so I can play my PS2 and wear my favorite pair of shoes." It just didn't make sense or add to the story in any way. How are those relevant to his character, in that moment?
I'd also like to see a little more variation in poses, like I get you wanna get these out quickly but all the characters stay in the same pose for almost the entire cartoon, and it disengages the viewer when you do that. You wouldn't even necessarily have to move them a bunch, you could just try mixing up the camera angles (not counting zooms) to tell a better story visually. You do that at 1:09 with an OTS shot, that's about it for their initial conversation.
That said, still a great job. Love the burnt hotdog line. Keep on keeping on, it's fantastic to see good, original parodies on this site again.
