It brings tears to my eyes
to see a pivot animation that has a Flash progress bar on it. I mean if you have Flash to make a toolbar with, just make a movie with it, and it'll be better received on Newgrounds. There's a legacy of hating Pivot animators on this site, so my personal advice: Use Flash. Even if you just have the SWF & FLV Toolbox like you said in the top of the screen, if you're willing to get an unregistered copy of that, you're probably willing to get a copy of Flash. Just saying.
But when it comes down to the animation itself, it's pretty choppy and unrealistic. If you are going to work on Newgrounds using Pivot, you need to be REALLY good at it. Otherwise, nothing you create will see a good score here on Newgrounds.
