I just finished this piece for Custom Home Magazine for a story about construction work. The sketch made the hands look as if they belonged to the viewer rather than this guy shouting so I had to work with them a bit to make them more believable. For the client, I had the word "listen" written within the mouth. The subhead for the story was, "Making yourself heard."
Note, with the heightened urgency of the Orphan Works Act, I've begun to add a credit to my web images.
Below is the sketch along with additional line work used in the final image.
