GIR Class Sketch

I had my first drawing class of the semester on Tuesday. One exercise our professor wanted us to do was draw half of a circle on the paper and make something more of it. It is obvious what I chose to make. XD The half of the circle is the lower part of his face, below his eyes.

Time taken: fifteen minutes.
