Focus is good, although I think it could be sharpened slightly or more noise added to the background. This will make the impact of those points of light in the water droplets and the intricacy of the leaf patterns/textures more startling, especially when compared with the "noise" you've added to the background, which I really like, by the way. It makes it feel as if you are looking through a window onto a wintry day but in reverse.
Framing definitely works. I like how the eye isn't only drawn to the droplets but also follows the lines of the leaf, constantly drawing you back and forth between the two (and also wondering what's beneath the leaf - what is it pointing to?).
The depth of field (aperture settings) work to excellent advantage, keeping us interested in the main topic but also vaguely wondering about what could be in the background.
The tones or lack of color/saturation adds dimension to the subject matter (winter) but I feel it is a little too overexposed if de-saturation is the route you want to go with this artistically. Possibly fix with some contrast changes or darken only the background?
Overall, the concept is very good and, for the most part, achieved. Excellent job!
