I once heard a useful tip when it comes to b/w processing. You should always consider converting to b/w when the colors in a shot were not interesting at all but here I get the feeling they were and I can“t help but wonder what this shot would have looked like in color, is it really more interesting b/w?
I want this photo panned to the left more, or at least show more of what is in front of the face. This could be very interesting, but I think the photo is almost half of the back of his head.
Also, I would have used more contrast. The desaturation looks a little bland. 5
