I like the idea of you having enough similarities to make the composition symmetrical, but I do feel like the skull and candle could have more difference to draw out the impact. I mean, the eye of the skull doesn't look too sunken due to the lighting, and if it were turned straight it may look more menacing, as if it's looking into the viewer's soul.
Also, the pattern on the wall behind seems to conflict with the message a little. The clean spot is above the skull and the grungy splotch is above the girl with the light. So if that was intentional, I'm not sure exactly what it's trying to say.
I do like the concept, though. I think it probably wouldn't hurt to crop the view in a bit, since the huge wall feels like it has its own atmosphere that's taking attention away from the subjects. It's good, but that's my basic advice if you were to try again.
yes, you are right! the skull and the candle don't stand out enough...but I didn't want to crop the pic even more. if I try it again, I would shoot it outside, maybe in a forest... I was very unhappy with the background...it just doesn't fit...it was blank white first...
