Visually arresting
Man, I created a Newgrounds account just to review this series. You seem to have invested a crapton of time in Fallen Angel, and you've got a pretty fantastic product to show for that. Everything about the way it looks is utter gold.
Unfortunately, the narration/dialogue/sound quality leave a little bit to be desired. I found myself staring in awe, completely ignoring the words coming through my headphones most of the time.
Don't take this too seriously, and definitely don't stop making this series (it's got a lot of room to grow,) but you might want to look into adding a few more people to your development team. It'd probably cut down on the workload, and it'd certainly let you concentrate on the animation. Which is just utterly fekking spot on. I got chills watching the scene where the Iranian and American nukes pass each other in orbit. Or when the old man with the pacemaker collapsed. Or when the surfboard went through the windshield of the car (some of these were from parts 2 and 3, so, uh, post-emptive spoiler warning, I guess...)
I'm definitely looking forward to seeing where this story goes.
