can you show us your scripts so we can see how youre formatting them?
very important question: when you script, are you imagining what your page would look like and then writing down cues to remind yourself later?
because if you are, especially since youre not working with an artist, i suggest you start sketching your pages as you're writing. im gonna just talk you through my scripting process to show you what i mean
so, i start by just jotting out the events as they occur to sort into scenes, and an estimation of how many pages this will take. this will be based on the pacing of your comic, but my rule is that in every update something must happen, and you must leave the audience with a question (what will happen next, who just came in, what did they notice?) so if youre releasing one page a week, make sure each page has a good hook and moves the story forward. if youre releasing four, you have a little more leeway.
so ive got my events jotted out, then i get those page estimates into something concrete. notice, however, that we're still thinking big picture - dialogue isnt tapped out, neither is panels. just what happens in this page, and sometimes notes on key visuals.
then shit like, really deteriorates in terms of detail...
BECAUSE, at this point, ive taken my page by page and ive started sketching out pages
im gonna use a different sequence for this next bit bc i changed my thumbnailing technique. so, heres the PBP for this scene:
it was a dialogue-heavy scene, so i roughed out the dialogue to help guide my thumbing
then i blocked* out the action, like a storyboard (these ones go around in a circle bc im weird with spacing, but you get the gist):
i see this point quite like film editing - ill often draw a lot of shots that i dont end up using. compositions will also often change from this point, since not all my panels are that shape - but it gives me an idea of my characters movement in space and what visual information i need to convey. that said, re: how many panels per page, i go for 5-7. any more feels pretty cramped, and any less would go too slow - though using 2 or 9 or 1 or 20 panels on a page isnt verboten, it should be used sparingly for impact.
while im blocking, this is where im noting down that script where i keep essentially just dialogue.
with these visual aids, i can move to designing the page:
so at the top with all the red, you can see that im hammering out the composition. i do 3 variations at a minimum - to mark them out i use the rule of thirds, placing a red line (i use yellow highlighter now, actually) to divide up the thirds of the page. theres also stuff with circles and the golden ratio, but lets leave that. you can see how compositions evolve over time - this isnt something that i could do with just words on a page, as you need to be able to physically see what youre taking about and follow the flow-line manually.
once ive selected my composition (the one with the lil star) i blow it up a little bigger and workshop poses. by the end of this process, ive got a thumbnail so detailed that i have no need for a script of any detail.
*blocking is a theatre term to refer to the actors planning their placement and movement on stage
tl;dr: you need to draw while you script to get a visual understanding of what youre doing, panel density depends on pacing, make sure something Happens in every update. also, every comic artist scripts differently, and its all about finding your own rhythm and noting down the information that you need
i really hope just going through my process helps somewhat!
