Help me with the snow

I went through the online tutorial for snow falling but im trying to creat an image over the snow and every layer i make it just has thesnow falling overit can you help me?

This is what Claudio was suggesting (see attached). Ignore the ‘graphics’ as I’ve just thrown the fla together to demonstrate the point, but I wanted to do a similar effect, with snow fall being seen through a window.
