What did you do for processing on this? There's a halo around her head... It's also quite underexposed.
I would suggest turning your ISO up. You were at 16mm at 1/10s. Generally you want your shutter speed to be at least 1/focal length, but in your case with the smaller sensor of the NEX Camera, you'd want to be at 1/30s.
I would have to go back into aperture and look at all the modifications. I made adjustments until it pleased my eyes. Would shooting it at 1/30 have benefited the picture even when I adjusted the contrast and exposure in PP?
