Good exposure. Very good expression captured. The background provides story details for the composition, and interaction of the subjects adds life to the photo.
Some areas of imperfection. The first being the hand - not so much of motion blur, but how a metal mug seems to be floating from the hand. It takes a second look to understand the mug belongs to the background, thus, becomes a minor distraction.
The next one being the "hidden" subject/s. Composition would be better if the face and subject of the person in the foreground (and the person she's covering) can be seen. The subject who's blocked serves as another distraction, while the facial expression of the subject in the foreground would complete the story. If a few more shots are taken in sequence, I guess that can be achieved. Still, I guess it's a compromise being a "moment" kind of shot.
