Now that is a nice set of white, hair. This man puts out a feeling of strength which you've captured. I think I would have preferred him placed either dead centre or more off to the sides...
A simple and casual street portrait - carries a bit of motion - walking toward you. I find myself drawn to the young lady behind him and the buttons on her coat. Not a bad thing - just where my eyes go. I like the nearly triangular composition formed by the people, too.
I love the character and expression you captured here. This has alot of potential but you could've worked with a 3rd of rules approach to get a better, stronger composition, maybe just by having done a tighter crop to achieve that would have been enough. My other idea to improve this would have been to convert it to black and white... as I can see a red circle from the traffic lights at the background which is quiet distracting and that could correct that and make your amazin candid shot the main focus of attention! Th way I vote tho is different from the rest here, I love the expression you captured and am givin u an 8!
