Another quick update. I am still working on the skin, mouth, and neck to add value and depth. I am not so sure about how the hair turned out ; hair is an area where I still need lots of practice with. Now, looking at the digital version of this drawing, I do see some imperfections I hadn't noticed when the drawing was on the drawing board. The new technique I am learning here is called the 5-pencil method by Darrel Tank and it does look like I still need lots of practice in that too.
