not quite there
I found this from the Review Request Club, so I understand that you've submitted this flash to receive comments on your 3d animation, so don't mind my rating, which I intend to be consistent with its context on the site. So, my comments:
1. There's an annoying pixelization effect, which is most noticeable with the top gun's left hand side. Also, they all need anti-aliasing.
2. The gatling barrels on the bottom guns are difficult to make out. Glossy reflective surfaces would help, or else better lighting.
3. I feel the lower-left gun would look better if we looked down at it from a slight angle, like 1-2 degrees. It looks so artificial viewed from 0 degrees.
