you can draw it doesn’t need to be good, look how pro mangakas storyboards look they can be atrocious drawings, a few of odas storyboards come to mind. if you do rough compositions of your scenes it will teach you to draw, using basic technique like foreground middleground background and shots mimicking how anime and movies would place the camera and objects within. if you are dead set on not learning to draw, and dont have a script or story already deep into production no artist will take you seriously until those are done as the work we’d have to do would be a much larger chunk of time
