Hey I saw your cartoon, it sounds like you want some criticisms so here we go, but bear in mind I'm no expert:
It was good for a first animation and had a pretty good concept, although it wasn't quite executed so well. That cry at the end sounded really wimpy. You should try sketching out your backgrounds on a separate layer and then clean it up on a higher layer.
That bit where he pulls up the blanket, his hands are really small, it would look a lot better if you made his hands bigger.
Before you make another cartoon, I suggest you have a go at drawing a load of stuff in the toonboom environment. You could have a go at more character designs maybe?
I've been really nitpicky here so bear that in mind because what you made was actually pretty good for a first timer, believe me I've seen a lot worse on the portal. Have a look on the portal at what other people have made, and read the reviews they get, and you can avoid making their mistakes too.
Anyhow I'm gonna add you to favourites cos I wanna see how you improve from here =)
