Concur with previous posters, lovely bokeh. Standard 50mm 1:1.8 lens? Great exposure, lovely colours. The candle has a beautiful texture, and the little mark to the right looks great. Composition is great and I like the fact that the flame is round. I might've got rid of the reflection of the flame or faded it a bit, slightly distracting, but it's your photo and I'm guessing you left it in for a reason.
