You got the idea...
Its good for a first, but then again, I doubt this was your FIRST animation ;)
I guess you have the most basic physic understanding, and at least you know how to insert sound clips and you had a crack at lip syncing.
Tips for next time: Dont do 'to be continued'. Ever. It only shows that you lacked the effort or ideas to complete your animation. Your better off just making something happen that triggers the end of the animation.
On another note, never EVER EVEEERRRR use chipmonk voices. Use your OWN voice, or pre-recorded stuff. Dont edit it. If you are too embarrased to say something without editing it, then you can always use the text tool, but use a nice font (NOT TIMES NEW GOD DAMN ROMAN) and dont keep the text up there for too long, and DONT use speech bubbles.
Good luck, but there is so much stuff I could tell you that wouldnt fit under the 3,187 words I can have remaining in this post.
