I think it's a nice photo, but the subject is just not interesting in my opinion. Try zooming out to show us a bit more of the environment. In MS certain types of candles are often used to ward off mosquitoes when we have cookouts or other activities in the evening. In that situation I might show the candle on a picnic table surrounded by food. Just my 2c.
The closest thing to it that would work would be if the table and candle holder were immaculate. And the molded rings on the bottom of the candle holder make it look too functional and less artistic. And the reflections at the end of the table would have to go. It would probably be a big Photoshop job to do all that.
