How-to do question: Animal footprints in snow

Hello, I am working on a a picture and would like to add animal footprints (in the snow). I have pngs of the footprints (black on trasparent background) and tried using color overlays and the Bevel/Emboss function, it is better than nothing, but net yet as I had in mind. It does not have to look as realistic as footprints in real photos, as the style of the picture is in between photo & illustration, and the footprints don't have to be deep, just hints of footprints. Is Bevel/Emboss is the right layer effect for creating footprints? I have never done animal tracks before, so advice would be great... thanks!
