Nice black and white here
Ridding the drawing of any color builds on "THE-TONE-OF_DESPAIR" or angst. The hard line work also maintains this tone by keeping a certain roughness around the edges. Shading works with the edginess of the drawing, despite being rather light. The heavy darkness around his eyes goes well with his hair, and leaves his personality "OPEN-FOR-INTERPETATION". Still, the assumptions will most likely point in the "DIRECTION" of angst, thus keeping the entirety of the mood in correlation with the tone being presented by the artist.

Some added shading and in the backround would be pretty cool.
