I'm not sure why I have such trouble getting well-focused eyes. But I do. And it drives me crazy. I used to shoot with manual focus all the time. Then I switched to auto, but I'm not sure how much that's benefited me. Sometimes it helps, but other times, not so much. Of course, now that I look at this shot, I realize that the eye in the shadow is better focused. Although not as sharp as I'd like.
There were too many colors going on with the red wall and green shirt, so I liked it much better with the b&w conversion.
