I like the variation in shades as you go down the candle. What is it? Or is this an "un-candle" with a flammable oil rather than wax as the fuel? Very sharp picture either way.
Did you try this at different exposures? I have a sense that it would be even nicer with less exposure. Glad I did not use that title. I do like the overall feeling of this picture very much. A 9.
If your flame were crisp and in focus, and there was no glare on the glass this would be a very nice image. The black in the flame is a great foil for the yellows and oranges.
