I'm siding with Raz on this one, a whole lot of that looked like you used a private server. While you showed some spots that some people may not have seen before, you didn't show anything special.
The editing was kinda cool, in a "not-so-well-played" Pathologist rip off way, and the music was more of an annoying distraction than a suitable accompaniment. Techno is generally suited to exploration videos, but you'd be better off trying for a more ambient effect. I would recommend for future videos that you borrow the style of "A Past and Future Secret".
Overall, it was a good attempt, and I'd like to see you make some more movies.
