Drafting Sections

 A technique I have recently learned is how to draft out lines effectively.

I decided to draw all my cross sections in pen, initially I thought I could not make any mistakes in fear of not being able to correct them. (Later I realised I could edit these in Photoshop). Nonetheless, I discovered, especially with trees, continuously drafting out shapes and then just following them with ink was highly effective in ensuring I was drawing proportionate shapes so I could learn to see the section before it was actually drawn.
