|Greetings from the Critique Club:
The brief for this challenge, Image Grain, was to use grain or noise to enhance the shot. This you did, thereby meeting the challenge.
It would have been nice to see the steps used to create this shot. But I am guessing you already had the grain/noise from using ISO 1600, perhaps a little more added in PS or a similar programme? The eyes appear to be the point of focus. Converting to B&W does add a certain appeal, however I think this could have worked as well in colour. I am not sure if it is the darkness of the shot or slightly off focus that makes the face appear on the soft side. Maybe you didn't use USM?
The positioning of your subject works very well. Also the near square format with prudent cropping makes this a competent photo.
I like most of what you did with this shot, but it looked a tad on the dark side for my taste. I do like the lighting on this, I don't know if you used off camera flash or reflectors but the lighting is even with no harsh shadows. The score appears just below what I would have expected, with it being nearer the higher end of the 5 or even 6. I hope this helps and is constructive.
