Look at the front of the frame on your shirt and that is where the camera has focused. It always happens to me when I do a self portrait too, my eyes are just wonky so I can never get the focus on my eyes properly :) You could have saved this a little in the PP phase by selecting the eyes, or eye in this case, and sharpening it up a bit, also maybe bringing in a little more brightness into the eye white. Lighting is good, the cross from shadows to highlights is both smooth and at the same time extreme, good work there. But like I said the main focal point is on the shirt. Thanks for sharing.
