My brother, the programmer, wanted to take a shot at creating a generic enemy for our game.  This is what he came up with.  For a guy that doesn't claim to be artistic, and doesn't draw, this is really fantastic.  The animation is so smooth it looks 3D.  I feel it could use some details (like a utility belt, or sash, or something), and maybe some aa.   Please give him any suggestions for improvement you can think of. 

10 colors plus 1 for transparency

24 frames animation.  Also, not sure why it's going so slow here, it runs much faster in gale.  It's set to actual speed in the preview dropdown, and all frames are set at a delay of 2.  I tried reloading it with one, but it is still slow.
