cant wait for the second part :D :D
Interesting indeed. There is an interesting begginng of the story, music fits, the animation is satisfying. The graphics aren't bad too. The only thing that it misses is some kind of action.
What we got here was a set of animations, scenes, showing what the character does. To be honest, the story is interesting, but the performance could occur quite boring to someone. I'm waiting for part 2.
Part one is, like you said, more for the introduction of characters and such. Things pick up soon, don't worry :) You can't have a nuclear war without action.
It looks like something really interesting is about to happen... cant wait to see what.
Also your animation is very fluent.
