Decent...
Graphics-wise, you did pretty well. The animation wasn't rough and the drawings were a LOT better than some other flash animations that I've seen.
I don't really get how 'style' works, so moving on...
Did you get the music and sounds off a free-sound website or something? The film-noir music was okay-ish, but the rest was just...weird.
Violence wasn't really your main focus, so that doesn't matter..
Okay. The humor was pretty good at times (the MGS bit with EVA was funny), but near the end it got kinda....lame. No offense or anything, but the complete randomness just doesn't go well.
Well, that's my opinion, anyway. Keep on trying!
