I grabbed your EXIF from your Flickr page:
Exposure: 0.005 sec (1/200)
Aperture: f/2.2
Focal Length: 35 mm
ISO Speed: 200
Exposure Bias: -5 EV
Flash: On, Return not detected
Take a look at the
DOF Calculator. When shooting with a pretty open aperture like f/2.2, at 35mm, you need to be a bit further from your subject to get focus on both eyes. Hope this helps.
