I've tried to make the snow look like falling. If you look at real falling snow, snow particles that are near look bigger and brighter, and move faster. Snow particles that are farther look smaller and dimmer and move slower. I've made three layers of snow, each wih two costumes which alternately move from the top to the bottom of the screen. It looks like a pretty heavy snow storm, doen't it. You may want to remix it to make it more peaceful.
