For water I have used fantasy film

I am not sure  that this is what is used by professional diaorama artists, but it works for me.  Here we have some new inhabitants by the water.

I am working on new diaroma's for my new phone edz.  (Marcus is a great help with this kind of thing, it is a great way to play together.  He has such fabby ideas).

More phone edz fun resulted in this

 a little lonely leopard.  She needs friends!
