Very calm image, and the simplicity is refreshing.
Since it is the Critique gallery - may I suggest sepia toning with a highly dilute bleach (1:10 or 1:20) to breathe a little bit more glow into the highlights? Just ever so slightly would lift this to even higher grounds.
Composition wise, play around with cropping from the left. With compositions like this, less is more. Great negative! Deserves experimentation.
