I am trying out a cast drawing this time, the key difference is that I use long continuous lines to start the drawing, I had to do many revisions since I am new to this method. But hopefully I got the shape relatively accurate this time in the end.
I am hoping that you can give me some feedbacks of this drawing.
Also, Could you explain a little bit how you understand the forms/structure around the mouth and chin area? (I usually do life drawing so when it comes to photo reference, I find it a little bit difficult to understand the form when shading).
