Had I been commissioned for your assignment, I probably would have approached it with an editorial style. The look I would have been aiming for, as Steven alluded to, would have been strong, but warm. Casual, but not too casual, and I would have used key lighting with a little fill bounce to sculpt your face and take advantage of the character that resides there.
All easy characteristics to delineate, not so easy to bring to digits sometimes. Typically these assignments really challenge a photographer, because unless the subject is one of those model types who can assume the pose when needed, it is up the the shooter to both bring those characteristics out in the subject, and have his or her lighting and compositional ducks lined up, simultaneously. Tall order for sure.
Here is a good example. I had 3 minutes with this gentleman. Key image in an annual report. Very high horsepower, didn't want to be in front of a camera that morning. 3 minutes to get to know him, warm him to whatever degree I might, compose, light, shoot and shake his hand on the way out. That's why these types of assignments run 2 to 3 grand for 3 minutes.
