I agree: sharpness ta ektu kom. Also, the BG is not isolated enough. Both of these problems have the same source: this is a relatively small crop from a 70mm 10Mpix candid shot. Since it's f/5.6, the DOF is pretty large: I should have used a longer focal length. Also, the photo was on the spur of the moment, so I didn't have time to compose the shot with the right parameters. Maybe I should have taken more time... that's the trouble with digital I suppose: I'm not forced to take more time in the photo
