It was really good, but...
This had some major issues mainly the lip-sync animation(like you said). Also at the end it looked like he was running in slow motion. You also need to make things look more uniform. While somethings look great, like the people or the robot, other things look bad in comparison, like the cars or buildings. I think your trying too hard to make it look good, at times the detail is really high, but then it gets lowed. The pseudo 3D look is a nice idea, but in the end detail shouldn't be sacrificed for it. I also watched this on youtube and the same problems still bugged me. Just rise the detail levels in your line work, lose the 3D look, and try using the simpler anime style shading. I think the whole thing will look better overall. Still great job, can't wait for the next one.
