What I'm going for visually is a harsh rain storm, where the rain decends at a very slanted angle from top right to bototm left, more horizontal than vertical... or however it should look given how the cloth is already positioned. I may add lightning but for now I haven't planned for it. The background I'm assuming will be some sort of dark cloud overcast.
(For the sake of size, I had to shrink it.)
Well, thanks for your time and help.
