Good but a bit messy
The art is great, the backgrounds are good, the sound is alright. Everything was alright except for most of the animation. I mean, incredible effort, don't get me wrong, but the movements are occasionally... I don't know.
Looks like some frames are missing at times: Like when he is on the toilet and decides to go, he pulls up his pants and leaves in a split second. That needed more frames and needed to last a bit longer. At scene 2, his hand and the chopsticks just vanish. As examples.
Another thing I noticed, which probably just happened once, but in the church, near the end, when Jazz sits down for a smoke, he and the other guy make movements at the exact, I repeat, EXACT same time. That little... thing... was a little uncomfortable.
However, this was still great. Good job.
