You have a nice progression on the right, a strong diagonal line, and bright flames that lead the eye.
I think story-wise, the candles on the right tell the story, and the ones lying down don't add that much. They may have some significance, or they might create some mystery about what they mean, but I think they damage the composition more than they help the story.
If the left half was just blackness, there would be nothing to distract the eye, and I think the negative space might work, at least some amount of it. But the dark jumble of candles does detract from the strong compostion to the right.
If you don't want to remove those candles, you could place them in the foreground in front of the lit candles, or you could crop half of them out (cut off the left third of the image), or you could change the perspective and shoot it from the right, so that the candles that are lying down are out of focus in the background, like this horrible sketch depicts:
