I could just utter one word after that: "Wow"
The plot was really something, I didn't expect an ending like this from what seems to be a sad story. Even though it was--well--in another language--I'm guessing Russian, I'm not sure so don't get mad--, but the subtitles helped a lot. Animation was smooth and very flowing. The sound effects were cool to. Plus, there is a really good message portraying in the animation.
Overall, It was a great watch from the beginning 'till the end. A brilliant work of art...
