Yea I use a script. I write and illustrate my own comic. My scripts consist dialogue and narrative. In my narrative, I usually detail character movements, expression changes, and action scenes(because action usually doesn't need dialogue to supplement it). Here's an excerpt from my chapter one script of BBS, https://tapas.io/series/The-Black-Belt-Society-.
The three goddesses of water, fire, and earth are sitting in the lofty heavens discussing the disappearance of their sister and their dog. Urt, the earth goddess, returns with nothing to show.
Otar: Have you found anything Urt?
Urt: No, Otar. I have asked the earth for the thousandth time, it speaks nothing of Ira.
Ire: We can’t go on like this. The skies of have become strange since she disappeared; Otar and I can only do so much with our combined power.
Ire’s hair is smoking at the thought. She is tired.
O: Yes, I know. We’ll find her, eventually, but . . . we might not be the ones to do it.
U: What do you mean?
O: Our creations, sisters, could be of use to us now. We blessed them with abilities that could find Ira.
I: Are you saying we should just trust some random humans with the responsibility of finding a goddess.
