You will notice i also extended the canvas on the final image and brought her dress down further. Her eyes were simply done in a separate layer and not so carefully covered over with a soft brush-in black. My black and white conversions always tend to lean towards whiter whites and blacker blacks. I custom b+w every b+w image i do. Typically bumping the yellows and oranges and a bit of the reds up to be lighter while bringing blues down a bit. of course it always depends on the colors they are wearing etc, but that is my general method.
