I did a little exercise map. I was inspired by one of my favourite spots in the forest near where I live. The lake is called Trehörningen (the triangle) and it has a very cozy wind shelter by the shore. In the area you can find lots of beaver architecture, and mires where sometimes moose can be seen grazing.

You can see on the lower right corner I started using a brush pen, but it offered too little stroke-control so I switched to multiliners 0.5, 0.25 and 0.05.
