I can only find a minor thing I dislike here: The sometimes choppy animation.
Other then that, this is just great. The b/w silhouette art style fits perfect to the grim atmosphere of the entire movie! You build an intriguing storyline, I doubt anyone who watched the first minute of this didn't want to know how it ends. The sound effects (gunshots, metallic whir at the flashbacks) add well to the complete work, too.
What I don't understand: Why don't you mention the other parts of "The Overseer" in your author comments?! I'm sure many NGers who watched this also like to watch the first episodes, I sure did, since you took your time & patience to create a rough, hard and unforgiving story arc!
Man, I like that stuff!
