Cool animation, nice job :) The character's motions seemed a little unnatural at times and I feel like the visuals could use a lot more work, but overall I think this has a lot of potential to develop into something very interesting. I'm not terribly familiar with 3d animation but I can imagine that it's considerably more difficult than traditional 2d animation, so props to you on that front. My suggestions are:
* Work on the character motions - make them a little more fluid and natural.
* Add a little more emotion (there were some scenes where the characters seemed unnaturally expressionless)
* Work on the art and throw in some more cinematics. There is definitely a lot of room for improvement on this front. Could use more detailed textures, backgrounds, etc. It feels like some of the scenes in this animation were too close together. Add some cinematic, transitional sequences inbetween them to add a little more depth to the story. Would be really cool to see an intro sequence like the one in the original GITS. I'd recommend checking out the movie "Blade Runner" for some additional inspiration.
Overall I thought this was pretty cool, so good job. Definitely a lot of potential here. 4/5.
