Quite bad.
Well let's get what you need to work on out of the way. I'm going to guess that you made those sprites in an outside program, hence the blue background blocks. If your going to do that, you want to save them as .gifs so they will have transparent backgrounds. (Or use the trace bitmap function).
It sounds like you didn't practice the lines before you recorded them - you need to put more emphasis in your voice. Also you need to get a new mic - since you have that buzzing problem. (Or if you use Audacity to record you can get a sample of the fuzz and it will cut it out for you).
As far as your trial running out, You don't need to spend 700$ on Flash. You can start with something cheap, I'd suggest Sothinks SWF program - since it's cheap and easy. Or if you want to go right to Flash itself you can find Flash 8 for just 300$ if you hunt around for a bit.
But you do have one talent here, you are good at sound effect placement, so keep that up.
