This one is very effective as is: great eye contactt. If you were to darken the hands slightly they wouldn't compete for attention with the face as much. Darkening the bottom of a portrait helps to guide the eye of the viewer to the brighter face and keep it there. It's a human perception trait. If the eye traverses a dark, unsharp area en-route to a brighter one it will not be tempted back there. In this photo the viewer will be initially drawn past the hands to the compelling eyes, but once they get tired of looking at them, they will be attracted away by the brightness of the hands and detail of the ribbon and rings. This illustrates an important point about hands and props: 1) Don't put them in the photo unless you want attention drawn away from the face, and 2) you can moderate the degree of attention they get by controlling their brightness and color / saturation
