Everyone seems happy. Two things I may have done... tried to capture a little bid of road between the edge of frame and her shopping cart wheels, and then crop a bit of the top off so my eye doesn't wander up there. Crop out unneeded stuff, it only pulls the viewers eyes away from your main subject.
What I really like about this is that everyone seems to be truly enjoying themselves. Makes me wonder where this is where grocery shopping is so delightfuly fun. A great catch - great moment in time.
