You can do better
Well, this started off reasonably well, but you've shown in the animation itself that you're capable of moving parts to the animations. Work on improving the intro and losing that "temporary intro" crap would make this a lot better.
Getting Fancy Dog to the moon was the best part of the piece - I like the tween that you put at the back of the craft for the flame. Perhaps a little more in the way of things to see during the flight itself. I think that you've put yourself in a position to develop this a lot further and give the public a much better finished product.
The ending was a little poor, losing out only to giving a badly drawn line image of a dog, that barely did anything. If you thought of other things to do when you're on the moon, then this could certainly improve the plot.
