Nice Work
It looks like it's in the the vein(sp?) of Take Back the Media or Bush Flash. I haven't seen one of these in a long time. Good work artistically expressing your opinion. It's even better that you backed up your opinion with a few stats sprinkled in there. You can probably strengthen your point better by including functional links to articles about the defense and oil industry's influence on politics ... so people don't have to just take your word for it. ;) Personally, I disagree that it's "purely educational" and would better be described as informational art.
While the art and expression of information is good, this can be better. The lyrics don't sync up with the captions for me, so that can be improved. The soldiers looked a little clunky. I know drawing with a mouse can be hard, but maybe some shading would help the look a bit.
Good work.
