Hi Andy,
to me, out of the three, I feel this is the one which has let you down slightly. It is still a nice pic, but not to the quality of the other two. The model looks bored, with a "I've had enough expression". The lighting is not up o the standard of the previous, being slightly blown out on the left and causing unflattering shading on the right of the nose (Giving the impression of a larger nose) The drop off of focus also appears to be slightly out, showing the eye on the left of the image slightly more out of focus than that on the right. Perhaps a lot of this is due to a low res upload, and I am not able to experience the true quality. But, to me this one is slightly sub-standard compared to the others. Sorry mate.
