In this image, I see, first and foremost, a car with a light blanket of snow, but only on the windshield. I am directed there by its being the only pure white thing in the photo. The rule of thirds, used well here, is used perfectly, and the scene retains its natural qualities. This is almost a still life that has many elements that give it interest and tell a story. Though the challenge is weather, and that is what is most apparent here, I infer from the clues in the photo that it is actually about Chicago itself.
We have some interesting geometric lines going on from the sidewalk to the yellow lines of the parking lot, and you've given us a snapshot of sorts by including the window frame on the left (or is that a building?) which makes it look like you had to shoot fast, or this scene of Chicago life would pass by quickly--good technique, though subtle. The inclusion of the garbage can is also a wonderful detail.
The mood is sombre and almost scientific, but not quite. Like I said before, there is a story being told here. Perhaps you will be driving the car soon and this photo implies a kind of relaxed, resigned dread. The drama is appropriately low, and your soft lines and focus enhance this feeling.
To improve the image, you might try enhancing the drama, even though it appears you want things to be low key. If so, then be low key enthusiastically! Perhaps different light, or a more dramatic point of view--even to the including of more wall/window frame on the left to give a sense of urgency would work. Think of your communication goals with the image, and then ask yourself how to really make this communication clear and dramatic, even if the drama consists of resignedness or cool, scientific interest.
A few voters below mentioned that the image was uninteresting, but I disagree. However, the things that work well for this very complex photo are not to be extracted or understood with a cursory glance, yet that is what most voters here at DPC give images.
In sum, I like this photo, and you should too. It is complex, whether you meant it to be or not, and the comlex elements work well. I'm sure that more people would appreciate a more "exciting" look or feel or mood, but that choice is ultimately up to you.
I hope to see more of your excellent work in the future!
Don't worry spring will get to you too :-) Good idea for a weather shot here. The pole or frame at the left is a little disturbing though, I would have either cropped it out or leaned more to the right to take the shot.
