 |  Example using DOF...
That comment was by Anouschka, but I added a similar notation: "I agree about using a narrower DOF to blur the background..."
DOF (Depth of Field) is a measure of how much of the scene is in focus, from near to far. Photographers will often select a specific lens aperture and focal length to throw the background and/or foreground out of focus. This helps draw the eye to a portion of the scene that holds the most interest.
In this particular photo, the background (and to a lesser extent the foreground) was a bit distracting, so using a narrower DOF centered on the row of flowers could improve the image.
Here's a very crude illustration, using Photoshop to blur the foreground and background to simulate a narrow DOF. The results would be more dramatic in a full size image, of course.
