Bearded biker in hat and shades, portrait on the forearm

A portrait of an older biker: full white beard, hat pulled low and sunglasses on, looking out with a calm, steady expression.

The face sits in the middle of the forearm, with the reflections in his glasses and the texture of the beard doing most of the work, and the lettering from his motorcycle T-shirt forms a solid band just above the wrist to ground the portrait and close off the piece.
