This reminds me of some of the older machinimas from back in the day.
It's got a certain nostalgic charm to it. There's clearly some issues with the HUD display consistency, but otherwise not a bad little video.
One thing I would suggest working on is your pacing. The scenes before the cornfield attack were pretty tight, but then the actual footage of watching f-18s attack stationary UFOs in roughly the same way over and over again was a bit boring and drawn out.
I get why they hid in the corn, but then they just sort of sat there and let the army blow them up, it wasn't much to see.
Again, not terrible, just a few things to consider in the future.
