Great Potential... But Not Yet Very Funny
Well, I would have to say this Flash didn't seem very funny to me at all. Granted, the idea is very original, and it has alot of potential, but until you get some really original stunt ideas, I think it will still be somewhat under-appreciated.
Here is what I would suggest :
1. Better stunt ideas. Jumping off of tables and walls just doesn't do it for me.
2. Clean up the animation. I know it is had to make a Flash, and I have a real respect for what you have done, but if you cleaned up the rough pixelation of the images and put some more detail into your animation, it would interest me a little bit more. Although I loved the real human heads.
3. More creativity in general. Instead of Arial or whatever standard Windows font you used, try something a little more modern for your English subtitles. Just a little cookie that would add to the overall presentation. Put more into the intro... you could even have a short clip of some funny stunt - sort of like a warm up (See Jackass).
4. Also, keep your mind open to constructive criticism and other general observations. One of the hardest things for me to do is hear how my Flash should be improved. But if you listen and learn (not to me, but in general) you will find you learn ALOT. But that doesn't mean heed the idiot comments... just try to understand other people's observations.
Great potential, but needs improvement. I gave you a 2/5.
