Looks like a fine portrait to me.
My first reaction, same as Beckwith, that a tighter focus on the man might be more compelling. On the other hand, I could make a strong case for the value of negative space. In this case, it seems to suggest the man's bleak outlook/future as well as his isolation.
Since it's a man looking into the camera, it's hard for me to make a case that it's "street photography." But that's open to broad interpretation these days.
I haven't gone into EXIF, but it looks like a 5D3. I'd like to know the lens and other specs too.
Thanks for asking.
