I realize it was your first, but...
First flashes are never good. Now, just because I am giving you a low score does not mean this is a harsh review. I am merely rating the flash on its merits alone.
I don't know the first thing about flash, and I doubt I could do any better than this, but that isn't the basis for reviews. It's based on how much the viewer liked it. That said, this is not something that was entertaining to me, or something I would watch a second time. However, that is understandable, as you are new to this. Do not let this discourage you. If you did, it would only make you worse off as a flash artist.
Get better, try again, and don't give up.
