Great shot! It's almost a classic exercise in great composition. You use the building corner, the road and the sidewalk to lead the viewer's eye right to the subject. The bright white spot on the building just pulls the viewer's gaze straight at the woman as she is walking along.
I particularly like the overall simplicity of this shot. There are complex elements in the picture; the cobblestones are busy, as are the flowers draping over the building, but they just work.
From a technical standpoint, everything is in focus and sharp. Perhaps the only niggling issue have with this image is the blown highlights in the sky above the house. The dynamic range of the scene has overwhelmed your camera's sensor.
