I think this video should be first in the series. It definitely helps things go smoother. I didn't realize this video was here until I got to the end. I ended up finding it by chance as I was doing the gesture series and was like "Why is he holding a pencil like that?" and found this video on Youtube.

I buy a lot of brush sets, and usually there is just one or two brushes I will end up using in a whole pack. But this one definitely has a whole bunch I am already using. They draw just like the real thing. If you like charcoals/shading, this is a pack for you.
