Agree with xray that the flare distracts from the main subject. Of course, one man's drink is another's poison...
You could try positioning your left hand or a piece of cardboard (make-shift) to block the street lamp if you don't have a lens hood handy.
Agree with xray that cropping the right side of the picture, plus giving the left more space may work out better.
But that's just me...
Hope this helps.
