Multi-Story Building Tutorial and advanced building techniques

Hey Guys and Gals!
I made a video outlining some useful building techniques for the current build.
Essentially how to build multi-story buildings the right way and a run down of the useful features of the slab tool.

Hope you guys like it. This one is a little more useful than the one i did before but i like to walk before i can run. I have more planned with some cool features and concepts.
If anyone would like to see something in particular done, let me know and i will add it to my to-do list.
