I think it is a very good one with a feeling, emotional expression, but the nose ring is to me rather disturbing. I think it would be better without it. My feeling!
I know it is a fashion Alessio as well as tattoos. Just clone it away and see what you think. The image is very good and very expressive I feel, due to her eyes.
I like this. Beautiful girls. I do agree with Martin about the stray hair. It is a bit distracting. There are also a couple of hairs over her mouth that could be touched up.
I like this also, Alessio and especially the processing you have applied. I mind neither the ring nor the hairs and like that naturalistic feel the slightly dishevelled hair etc give. The one thing I do find slightly disturbing is the slight tilt to her head that makes the eyes not level and that, in some way, makes it seem as if she is not engaging fully with the camera.
