To me this is a nothing shot. What I do appreciate is that you anticipated that a shot was about to occur and swung into action. Keep practicing, next time maybe you'll be a little faster, maybe the frame will be square, maybe the focus will be on the subject and maybe the pedestrian will have a reaction worth capturing.
As I'm walking up/into an assignment, I'll adjust the cameras settings based upon what I am seeing from afar. That way when I'm actually there my settings are reasonably close to what I need/desire for the shot. Going from inside to outside I'll adjust the camera or outside to inside. (I don't shot in auto.) Pre-thinking settings saves some time and helps with previsualization.
