I love the light on the bubbles in this one. I have found that macro shots really tend to emphasize little details and with that said, you might have wanted to clean the top of the candle before taking this shot.
it's an okay picture of a candle. lots of bubble in the candle. some color, some lighting coming down from the top. I would like to have seen some of the lit wick for contrast and flare, you cropped the top off when perhaps you should have shown the top instead of the bottom.
