Nice explore. I miss the trees and greenery sometimes, living out in the desert. You may want to consider editing your video for length a bit as 20 minutes is a long time to hold someones' attention. I am pretty new to video stuff too but I've also found that bringing in titles and transitions makes the world of difference in the final product (more like the warehouse video you did). If you are anything like me though, be prepared to spend a lot of time editing even short 5 minute videos and encountering the new-found appreciation for how long it takes to cut a movie.
Also, you can embed your future videos if you'd like by using the embed tag. I think it makes the post look much more interesting instead of instantly diverting someone to a different page.
The embed tag looks like this:
[ youtube = JyVl5NUihpg ]
But without spaces. The stringy of letters and numbers that you need for the tag can be obtained from either the youtube URL or the share URL. In the above example the "JyVl5NUihpg" string is unique to your video.
https://www.youtube.com/watch?v=JyVl5NUihpg&feature=youtu.be (In this URL it is the string after the "=" sign and before the "&" sign.)
http://youtu.be/JyVl5NUihpg (For the share link it is just the last string after the "/")
When you hit SpellCheck and Preview before posting, the preview should show the youtube player just as it will appear to others reading the final post. If you get a blank box it is messed up somewhere.
It will hopefully look like this when you are done.
