The width of a circle

This is an Illustration of the song "The width of a circle" by David Bowie.
The song really has some interesting lyrics! This is really just the first part of it... I planned to make a second drawing of the last part, but when I started analyzing, and I found out what he really meant by his strange words, all my plans crumbled.

I still wanted to try, but the sketch turned out too weird. I just had to stop before it went too far xD

(I didn't really think too much about making him look like David, except for his hair.)
