Technically, there are a lot of things wrong with this photo. It's a little overexposed. The bright towels in the upper left draw your eye away from the main subject. The zoom lens was set too wide, making her hand look almost as big as her head. The big cup in the foreground is distracting.
In this case the overexposure was fixed after the fact and the distracting bright background and cup were slightly minimized with a vignette. Not much can be done about the perspective. That's the type of thing you need to think about before taking the photo.
Sometimes you just grab the camera and shoot. I think that may be real meaning of "snapshot."
