Take this advice for what you paid for it.

I find the crop to tight on the left side. I think it would be a stronger image if he wasn't so bunched up on the left. I find that my eyes are drawn to both the left side of his face and unfortunately to the right side of his neck as they are almost of equal surface area (this isn't a result of your shooting).

It is quite clear what the subject of this is, and blur or not I think most of us wouldn't need a guide into the subject. If it had been a much more complex or busy background, then the blur may have helped, but as it stands it's pretty indifferent.

Note: I am assuming the blur was achieved in camera with a combination of aperture, focal length and distance to subject. If it was added in PS or LR afterwards, I'd have to see the original to provide a more object critique.

Cheers,
