I didn't vote on this challenge so this is the first time I've looked at your image critically. I'm impressed by the number of comments your entry generated. This shows that this image has a lot of character for such a simple subject. It is easy to tell that this is a candle that is actually used and has been for some time. The angle of the wax drippings show that this candle was not repositioned for the challenge. I like that aspect. The one suggestion you could try if you decide to ever shot a similar subject would be to shine some soft light on the body of the candle. This could be from a flashlight or any small light reflected from a distance. What this would do is provide additional light to the image, which would allow you to increase the shutter speed slightly and would produce a bit more detail within the flame. However, for this challenge that might not have improved your score, as it would have given the body of the candle more prominence and the flame might not have be seen as the primary subject. I really do hope you attempt to re-shoot this entry, as this candle could really shine with a little experimentation.
A larger file size should help with noise. I think this woul dhave been better if the candle had been standing straight up instead of leaning. But I love the shape of the flame, and how the candle blends into the background so nicely.
