Hey guys! I'm going to step you through my process of making a page. I'm not claiming that this is the 'right' way of doing a comic, or even an especially 'good' way, but it's my way. I cobbled this method together through trial and error and I find it works for me. I found out a while back that Stan Sakai also uses a similar method, so at least I'm in good company.
First thing, I don't work from a script. All the stories I've done so far with Much are based on outlines I co-wrote with my pal Tom Pajak. First we brainstormed as many scenarios as we could think of using my characters, then we put together two or three plot threads that complimented each other and Tom wrote a rough synopsis. We refined each synopsis through e-mails back and forth until I found I had enough material to start drawing. I then broke down the story into 'beats' which are basically all the individual things that need to take place for the story to make sense. Sometimes these are individual scenes, sometimes a single line of dialogue or sometimes just an action by one of the characters.
The next thing I did was start sketching thumbnails. This is the part where I take the information I need to convey in the scene and try to figure out a way to make it entertaining. I usually put in placeholder dialogue if I use any at all. I like to leave that for the end.
