I like it a lot and it seems original. I think you might want to tone down the flame a bit because candles don't usually have such a big flare, but then again, you might not be able to hide the skull in there if you did. :\ Still I like it a lot. keep up the good work.

edit - if you feel like going back and improving upon this piece at all, you also might want to show where the candle has melted down the sides as well. Sort of has that "plastic" look to it right now.

good job dude!
