What is the "best practice" for describing the layout of panels in a comic script? I have already done the layouts for these comics, but can't draw, so I want to write a script to give to a potential artist. I'm not sure how or where to describe the page's layout with respect to panels.
The way I've been doing it so far is to put a description at the start of each page where I say something like
Page is divided vertically at 40/30/30 and each row is divided horizontally at 50/50, where the numbers are in terms of percentage of page height or width.
Is this the correct way or is there a better method?
For tools I am using Scrivener + this workflow guide.
