Your technique to produce this shot was truely painting with your camera and produced an entry that really met the challenge.
I like the flowing lines of light that create an intense set of curved lines. You filled the frame well with both symetrical and random light.
Because the dominant color of the lines is white, your white border accents this. For me the softening/blurring of the border detracts from the graphic, hard edges of your compostion. A contrasting black may have shown off the other vibrant colors.
