Inspired by the question: How to design characters for a comic series?
The question is broadly about both creating a character team and art technique. The OP has been directed to Arts and Craft and Graphic Design, which are about technique, software, and specific crafting skills. Those exchanges don't cover narrative questions like creating a comicbook team, signifying through visual cues or worldbuilding through visual images. (All 3 links are valid topics on WritingSE.)
Notice the subject of building a comic book team is allowed when the art aspect is removed, but that actually makes no sense because a comic is primarily a visual storytelling medium, and comic characters can't be divided from their visual design. A similar case could be made for other audio-visual narratives.
However WritingSE makes exceptions about graphic design when the tools and techniques are about formatting text on a page or creating a book as a physical object. In otherwords, graphic design questions are ok if it is words, but not where it involves a visual-oriented narrative.
We have several tags where another media component is implied: https://writing.stackexchange.com/questions/tagged/comics https://writing.stackexchange.com/questions/tagged/illustrations https://writing.stackexchange.com/questions/tagged/videogame https://writing.stackexchange.com/questions/tagged/screenwriting https://writing.stackexchange.com/questions/tagged/script
Many answers under those tags silo the discussion into separate "writer" and "artist" roles with advice commonly phrased as "writers just write, the artist will make the art decisions."
We have a bit of a disconnect. There are situations that can be neatly divided into writing or graphic design, but there may be questions where they are inseparable because the visual is narrative, and vice-versa.
Please consider this a lukewarm proposal for WritingSE to allow for all narrative discussions irrespective of media. When a question veers into specific art-craft or technique the OP can be steered to the proper exchange, but where the question clearly involves character and storytelling we should not send the OP away. There is no other exchange to discuss creating a narrative.
