I agree that for a first try, this is not bad at all. Also, I can't pretend to know anything about how an animation program such as this would be used. However, I think I might be able to point out a few things that might help you in any future attempts.

First of all, it seems you shrunk her, then decided to take away some of the more mature features, which resulted in a very wierd process, to say the least. I should also point out even after it was done, she still had developed breasts, though her body was that of at least an 8 year old. Also, there does indeed seem to be the illusion she is "deflating" instead of reducing in size/mass so you might want to consider having a more even reduction around the body, instead of the bits and parts you did in this version. I understand, of course, it was a first try, but hopefully on your next one you will be able to make one even better.
