Which portrait seems most authorial?

With a new camera and tripod, my husband, who is the real photographer in the family, decided to turn late yesterday into a Beth photo session. "You need a real author's photo for once," he said (and judging from the comments I've received on other of my book-jacket photos, I reckon I do), though few things make me as self-conscious as sitting in front of a camera.  I was feeling especially self-conscious yesterday, for I'd spent twelve hours of it practically immobile, staring at a computer and talking to the screen.  Whatever.  Bill set up the lights.  I put on some lip gloss.  He took 30 pictures, all I could stand.  He's a talented guy (those who know me in person can attest), and he just sent me three photos to choose from.

Which of these, I wonder, would you most want to encounter on the back of a book jacket?
