The blurry elements (the people) are in the background. Doesn't really add much to the image. The intersting stuff is (more or less) in-focus, brightly lit and in the foreground.
not really fun enuff of an image here,a crazier camera movement may have created a wilder effect,intead of relying on your subjects to move,try moving your camera to create blur.
I see from the lady's face that you used a longer shutter speed to introduce blur to the image, however, I feel that a 'shaky' close up of the sweets(?) next to the cuddly toy or a blurry shot of the colourful bears may have had more impact.
