I’m working through a self-study drawing website, and I’ve made it to the shading lessons. Shading is great for creating depth in a two-dimensional world. 
The first shading technique I was taught was called squirkling. It involved making random rounded squiggles of varying size and pressure to shade. I’m still trying to figure out how to do this because my mind really just doesn’t wrap around it.
You can see the changes in values, and it almost looks like it might invite some depth, but I don’t know if it really pulls the viewer in.
A few lessons later (also known as this morning), I hit the next section of shading lessons. These lessons focus on hatching, lines drawn with various spacing and pressure. The different values of the mountains and the sky are clearer here, but I almost feel that the hatching lines keep the viewer from being pulled in.
What do you think? Do you see the depth as the mountains become lighter in value? Do you feel pulled in?
