I really appreciate your lengthy comment!! And I think you have a good point about the 'slider style', definitely one to think of!
About the length, I think people having interest in buying such a house can watch the video for a bit longer than people not seriously thinking of buying something, but I think I could certainly be shortened at a few points.
About the tour, I did not intend to make it look like a tour, because it should leave people something to think of and keep interest. And although it was quite hard to make a tour, because it should include hallways (which are boring) everything was edited quite logically, not totally random.
I just love to film and think there is market in the place where I live and think real estate is a market that can give me jobs on a regular base which is why it's interesting. But it is definitely not something I only want to do! It was my first real estate video, so your comment is of great help, thanks!
