* The sun in the frame is one problem. It over powers the image and introduces quite a bit of flare. When shooting to include the sun you're really best off using a prime lens. In this case, you would also want to use a Graduated Neutral Density filter. These filters are darker in one half than in the other, allowing you to expose both the sun/sky and ground without over/under exposing one or the other.
* If you were to reshoot this to keep the sun out of the frame, but still keep a similar angle to the sun, you would definetly want to use a lens hood and/or shade the lens with something to reduce flare.
* There are a lot of artifacts in this image. I'm guessing consumer film developed at the local drug or grocery store? Avoid such places like the plague. They murder film. Find a good, reasonably priced pro lab in your area which will keep your film clean. Also, you can get pro films (finer grain, sharper, better color rendition) at places like B&H often cheaper than consumer films locally.
* Finally, I think I would have composed to keep the tracks out of the frame.
It is an image with potential. I hope these suggestions help!
There are a couple of things wrong here; first is the sun it?s self, it should not be in the shot. The real shot here is the warm glow of the snow and the shadows that are being cast. Next is the overall ?dirtiness? of the image, there are a lot of scratches and blemishes here. I am not concerned about then when posting here just that you should be aware of then if and or when you want to make a print of this.
So what I would do here is crop out the sun and adjust the levels to help bring out the detail in the snow and shadows.
I have attached a fix to help illustrate what I am saying.
