.. pretty good, I admit.
One minor gripe: I don't think the music matches what's going on the screen, songs like these work better for flashier editing. It's definitely a good thing you didn't go with "Imma giev you seizures with mah lazors!!1" special effect rave party, but SOME effects (that matches the music) would have considerably improved the presentation. Sometimes less is more but none does not equal most, if you know what I mean.
Just to give you an example (I know these aren't Legions videos, but hey-ho), here's two of my T:A videos that have minimal effects in them. Notice how different my music picks are compared to yours despite having very similar editing style:
I'm not trying to be obnoxious "I'm better than ya!", I merely want you to compare these to your video and consider how they differ from one another. Which video has best presentation, I'll leave that to everyone for themselves to decide.
And no, I'm not forcing everyone to watch T:A videos. If you don't like T:A don't bother checking either of those videos.
