Beautiful, for the most part
Let me start by saying, I loved the style and art direction of this video. Many parts were drawn very well, and the music fit just perfectly. A great job overall.
That being said, there were a few points that took away from the whole thing. That first bit with the bleeding guy made no sense in the whole piece, and even less when you see him alive all of 5 seconds later. Also, watching the rider change positions on the bike looked awkward, perhaps keeping his movements minimal and letting the bike be the centre would have been more effective. Lastly, the act of waving the flag of an enemy base in the air only makes sense if:
1) the base is actually conquered, which it didn't appear to be, and;
2) there's actually someone else to see the flag being waved. The inclusion of someone seeing the man's victory would have been much more meaningful at the end.
