Well the bottom is just a bunch of big grey squares, I don't know if this is supposed to be an effect or or what, and there are vertical lines running through it which kinda cut up the image (again don't know if that was on purpose but personally I don't really like it a whole lot).
Also as I think Aikido mentioned earlier, it doesn't loop, and in .my. opinion images like that which have a short animation and then jump back to the beginning look silly if they're short and especially if they're a banner type image.
Just my input
Heh sorry, [Secret] is a tough clan to please.
