Don Kihot (1961) watch online HD

Don Kihot was the third animated short from Zagreb Films that I discovered on YouTube as linked from Cartoon Brew. The translation from the title is "Don Quixote". The animation seems to be that of several flying faces after this one person who may be the title character. He keeps getting away from them with help from a sidekick who is supposed to be Sancho. Near the end we see a realistic-looking windmill. I have to admit that while I was fascinated by the imagery and many of the sounds, I was a little confused by this short. Still, it's mostly interesting to watch so on that note, I'm giving this one a 6. Maybe another commentator can tell me what I just saw here...
