My array doesn't scale down when adding the array count.
At 8:17 you do something superfast without saying what's going on. Doesn't hurt to just say "shift+a to add". Since there is no place here on CG Cookie that bridge between the super fundamentals (building the space ship) and the rest of all Blender-functionality, it is quite a ninja-task to follow along and figure out what is going on.
Or - if there is tutorials as good as the SpaceShip that goes through Shading, Materials, Lighting and so on - they should absolutely show up as the logical next steps after the SpaceShip. Now, I have to randomly jump into tutorials and buckle up. :)
