Nice!
The character designs and art direction is cold! I love your style, it's got that messy, untamed feel to it. Also, the voice acting fits the characters, and your backdrops are just about flawless.
Thing is, there's some problems with the way it's put together in some areas. Sometimes, it looks like your characters have nothing to do with the backdrops whatsoever, you'll have people walking and it doesn't look like their feet are propelling them forward at all, just an animation and a static background that have nothing to do with each other. I hope I said that right... Also, where some of the backdrops are JPEGs, sometimes they don't fill the whole screen, and there's this white line on one side of the screen, I might just be nitpicking, but it sticks out to me... Also, I see you like having lots of shading and detail, but at times, it makes the animation suffer, I would like to see a lot more frame-by-frame that's redrawn and not just moving one static drawing.
Otherwise, it's really good! Definately stands out from most NG's stuff, though I'm not too fond of the storyline, but I won't take points off because of my own personal preferences, it is highly original and pretty well-executed. Keep it up man!
