One of the drawings I started during my most recent Picarto stream. My focus for that stream was to go in some more depth about the mental process and techniques I use when I’m drawing.
 
During the second hour of the stream I discussed how one can use construction lines to give a figure depth and solidity. Now, since I’ve been drawing for decades I will often not use all of these construction lines, but I decided put all of them in this drawing to show how they can be employed.
 
So I started this drawing of anthropomorphic Tempest Shadow during the stream and here’s how the finished drawing came out.
