Very, very good video. I especially like the part where the UFOs emerge from the moon's dark side.
The only thing lacking is the impact. It would be better if in the next incarnation you can make it so that the music coincide with shots fired and the aliens dying. (But then you will have to find a different music track for it so I don't know if this idea is feasible.)
Check this out:

For me, it's the best fan-made video ever. It's about Tribes: Vengeance but I like the way the music and the shots are timed. It has that "oomph" factor; something that, in my opinion, should be in every trailer with guns as it maximizes "oooh"s and "aaah"s from viewers.
I hope this is useful.
