I would emphasize the clock more, by cropping tighter. Take some from the left losing the lower window. Crop up from the bottom losing the lower windows and a bit from the right losing the vertical dark bit. This will leave the branches nicely framing the clock.
I have just seen this image (as cropped) and I do like its composition and find the subject interesting.
But, on first look, my eye/brain questions why the snow on the clock is so bright white and the snow on the surrounding tree and wall is so dark and dim. To my eye, it looks "unnatural" and "faked" (darkened in PP).
So while I do like the image, my eye/brain expectations are that the white snow surrounding the clock would also be bright white.
Was the surrounding snow "brighter" than it appears here in this posted image?
Assuming so, My Simple Suggestion: post the image showing the surrounding snow in its "natural brightness." (Post the photo as the camera saw it, adjusted/converted to BW.) Post both so we can see.
The snow was darkened in PP around the outside of the clock to show more emphasis on the clock but I did it in LR and I just now realized that I can do a levels adjustment layer and mask it in photoshop to keep the snow bright.
