I know it is your first submittion and all, but.
There are so many easier ways to do that, Trace bitmap being one, and just magic wanding it out with flash the other. As a tutorial I found it had to follow, and annoying you had to click you way through, and it was very disorienting with the zoom in on menus. Also, I understand recommending gimp, but once again it can and should be done in flash.
