Here's my honest opinion:
Too many crappy Movie Maker effects.
Keep effects to a minimum, especially when using Windows Movie Maker
Only flashes, slowing , speeding should be used.
Not screen colors and squishing effects.
You had lots of dead time (You just running around, and not killing)
You also had lots of noob kills (Headshot an AFKer)
and you cut the clips too early, or too late.
Try to focus on the clipping first, and try to get rid of dead-time
It's not hard to get Sony Vegas Pro 9.0 for free,
it's so easy (Insert Geico slogan here)
(Good for a first montage though, i've seen MANY shitty ones)
Also, try to fit good music in (Not saying your music sucked)
The song you used isn't really a montage song, or well it didn't match your montage.
Try to find a song with pauses + good beats etc; (no rap music please)
Good job though
Okay fine then, so i'll stop saying you spam,
if you think about your threads or posts before you submit them
Think of these factors:
Will a majority of people like this thread/post?
Am i contributing to MPGH?
Is there already a thread about this, or am i duplicating a said post?
Does this thread/post have any meaning?
Think about those first!
Be cautious, or Spam Police like me will be on your trail
By the way, you shouldn't make demeaning posts,
If you haven't contributed to MPGH
(You really haven't, i looked at your threads)
Then don't talk shit >D
