It looks a little dark, but I'm at work on an non-calibrated monitor. I'm not a fan of the angle as it doesn't add anything. I think a few inches back would be better too, but keep the framing roughly the same. The flame in the right third works, assuming the flame itself is your subject. Speaking of which, if the wick were longer and you were getting a bigger flame you'd have more light and probably a whole different picture. When photographing a light source I try to remember that a sunset shot isn't about the sun, but about the light hitting everything else. Most times the same theory can be applied to other light sources. Candles can create interesting light and shadows, so keep playing with the subject and be sure to check how it affects things around it.
Also, this is the first critique I've done on here in quite some time, so I may be out of practice.
