If you google "umbrella in snow" under images, you'll see that this concept has been done many, many times. That doesn't make it bad, but it does take effort to make the image stand out. In your version of the image, the things that are working against it are the busy background (especially the poles which break up the lines formed by the cars and the sidewalk), the lack of sharpness anywhere in the image, and the rather dark center figure. To make the image interesting to a viewer, you need to create some kind of emotional link, and certainly most of us will relate to a person holding an umbrella and walking through a snowstorm. The trick, however, is to simplify the image so that we can clearly see the subject (and even blur is acceptable IF we can connect with the person), and relate that person's situation to the surroundings. To do so, you can either find a vantage point where the background is less busy, or use a wide-open aperture to create a thin depth of field which will also work to suppress the background clutter.
