Beautiful tones and bokeh and I love the sharpness in the reflection! The only thing I would have done differently is to take advantage of that gorgeous natural curve and lifted the overall composition a little higher and to the right so that the leaf is a little more in the top left corner; having it almost center seems to weaken its presence a little. But that's just me. This is a gorgeous soft piece with beautiful colour.
Oh this is a beautiful shot! I love the reflections in the water and the cold winter tones of the piece. Did you filter in photoshop at all or is this natural? The very tiny hint of bokeh in the background softens this up just nicely too. Well done!
