Ok ok ok, after re-visiting this thread, i realise that we haven't really been giving him any constructive criticism, just flamed his ass.
Tip 1: View your own video before even showing to another living soul. Therefore, you can see how absolutely s****ty it is or how good it is and start again.
Tip 2: Use music, it's a very good way to set the mood of a video and if your choice is good enough sometimes your viewers will be screaming or dancing along with the crazy heavy metal soundtrack you just put in.
Tip 3: Youtube? NO, NO, NO!!! Bad! Bad! A bad quality player like youtube will give a bad quality video and believe me, many people's eyes bleed after watching crappy soldat videos there. It's true.
Tip 4: Gay repetitive sound effects (eg. "BEEKOMGlulzGOODsoundLUL!!11!!!" or "B00/\/\ HEADSH0T!11!!) makes we wanna just walk outside and shoot someone. In your case, after hearing the first "Beek" sound, I immeditely wanted to go kill myself. Luckily, I'm a nice guy and IF I did die, I wouldn't get my family to sue your ass for murder.
So if you take these little beggining tips into account, plus many more. Hopefully you'll produce a movie worth the 3 minutes of peoples lives.
Oh and, good luck.
