Matt, I am so glad you posted your drawing of your son. It is beautiful and so emotional. You captured the “crossroads” nature of his age.
My drawing for the week: I drew this image and tried to match values several times. My values lack gradations. They look harsh. I tried to build up the values like you suggested and I tried to use varying line. I welcome your comments and suggestions. Again, I am so happy to be part of DTO! ( I am not sure how to download the reference photo but I’ll give it a try).
