Holy crap, this animation is amazing. Very fluid, and the subtle reactions are great.

Something about this is kinda off.

This is really hot

Yup.
While being amazing & well done the motion is tad bit too linear and even.
Due that the motion has mechanic feeling. By adding another "dip" to the loop with slight varation it would seem more natural & organic.

Especially that darned left foot.

I think it looks odd because of his reliance on those 3d models he has been using to assist him, that and the apparent lack of movement from the dom in the back.

The guy in back does move. It's subtle, but it's there.

I think it might be all the straight lines. I've seen other animations where the movement is just as straight as this, but it doesn't feel "off" because the characters have realistic curvatures and whatnot. All the straight lines here just makes it seem even more robotic and fake.

Given the motion of everything, I'm thinking this is actually a 3D animation that has a line-art texture placed upon it.

Go all the way down I could take all of that.

Hehe me too

looks like has draw over 3d models.
It doesnt look like traditional 2d animation

Perhaps he used a technique similar to rotoscoping, but with a 3d animation instead of a real video.
