It doesn't look particularly noisy or oversharpened to me. Overall contrast might be pushed a little too hard, but that's just a matter of taste.
The main issue I see with this otherwise quite decent photograph is the missed focus. It seems to be slightly in front of the nearer eye, and it should be further back. Since the face is turned, you really want more depth of field to get both eyes in focus -- at least that is what is usually done for this portrait -- which would make it easier to get the focus looking right as an added bonus.
Well done, though! Nice light, an appealing portrait of an pretty and pleasant-looking woman.
