If your got more of the woman on the left in the frame without cutting her off, it'll be better. But this is nitpicking a bit because you needed a quick reaction to take this shot so I think it's great.
This was shot blind, but I chose to not take the tilt out because it's a very Winogrand shot. All about the lines of gaze. And Winogrand was all over the place with the tilts.
I don't much like Winogrand, but I kind of like this
