Now that's a shame! Not sure about the composition here it is a little weak, it does say all alone but perhaps the furniture and other peripheral objects take the focus away.
Great image, nice emotional impact. Definitely fits the all alone description. Use of black & white is exceptional as is the lighting and focus. Very well done. This is such a sad image especially with the title, made an immediate connection. 10
Yes, I think this photo gives a very good feeling of solitude. technically seems the model's face is a little blurred and focus is more on the table then on his eyes. But well, I thik the important is the feeling it does. Probably a darker look would fit.
