I want to know how many hours went into this.

I've played around with Blender, and this seems like it would take months of effort. But for a professional with a decent workflow and total knowledge of the tool, how long did it actually take?

It doesn't answer your question directly, but watch the "making of" video: https://vimeo.com/188964250 - it should give you some idea.
