the back of the neck isnt really apparent, its hidden by his thumb. I saw that but was seeing it through the color (purple/mauve gloved hand ) making the whole thing pop more. Thats a sideburn. Its not a serious piece so it has a slightly cartoony lean.
The glasses are meant to be oversized like 70's glasses.
I saw this 18 year old girl wearing a pair. She actually pulled it off, she was very pretty but somehow it looked good on her even though on most of us it looks dorky.
Thats where I went with that.
This isnt a heavily thought out piece just a for fun, see what comes up on the page. Its about keeping loose for me and these light hearted drawings keep me motivated to draw more serious pieces.
