It would have been funnier if it weren't so slow
It just kind of dragged on and on... And there's a major sound sync issue going on, which doesn't help much.
First thing I noticed is that you mention yourself twice at the beginning of the thing. I understand you're proud of it, but it's redundant, and makes you seem kind of stuck-up. either get rid of the way-too-slow-motion pogo stick guy bit, or get rid of your name in the too-slow second bit. And either way, make them go faster. Waiting for the pogo stick guy to get across... Then waiting for all the words to appear... It took over 30 seconds just to get into the cartoon, and that's all "Come on, get on with it!"
Once I got to the cartoon, the sound sync issue became apparent. The olympic announcer guy says his thing before the wheelchair guy even finishes his thing.
The fat guy on motorcycle thing had the same issue as the airplane bit.. That is the engine noise was only occasional. Was like RRRRR....................RRRRR......................RRRRR..
.................... Really annoying.
When people talk, it's nice that you did animate their lips properly, I can tell you worked at that - but because the sound isn't syncing right, they continue to move their lips well after the talking's over.
Every bit of animation in the thing seems like it's in slow motion, and the sound is a problem throughout. I had to go watch another cartoon to make sure it wasn't just my comp, but the other toon played fine.
Frankly, it's very much like the framerate on the toon is half what it should be, or the sound is set to event instead of stream, or a combination of the two. Also, did you optimize your graphics? That'd slow things down a bit if you didn't.
Anyway, it's a great effort, If it weren't so sluggish I think I would have enjoyed it a lot more.
