A very good diagonal composition in the square frame, I like the quiet mood of the picture, I agree with Bob the highlights in the top right if the frame tend to be distracting, but I appreciate this is a neg. scan and can be easily toned down in printing.
I did the shot quick and my co worker was not aware till she get it on her email. I first want to capture her image talking on the phone. But she finished after I focused and snap. The Zeiss round glare lens signature on the upper right is similar to my Summicron 75mm apo, for my 35mm film; that is not as conspicuous on my Summilux 50mm asph.
