A little bit more contrast between subject and background colors may have helped. Otherwise I think this is great - it seems alive with motion, as if the cord is being dragged along the floor. You captured "fire" in a creative and beautiful way.
Looks like it falls under the, "Don't try this at home" catagory ;-)
Intersting shot, good composition going across the screen. Might have used PP to darken the background closer to black for greater effect.
