Narselon...
I'm not an expert but i've been trying something lately... I just write the dialouge and worry about description later. What works for me might not work for you.
In my screenplay, which i've posted by the way

In scripts and plays

I wrote the dialouge and some VERY basic onscreen directions as well as to what I want to do with it. Keep in mind (if you do read it) it's a VERY rough draft.
Keep writing though.
