Hey there. I am new to this site and i think that it is a good community(do check out my work guys!)
So i think a good story, wether that be a comic strip, manga, light novel. If a story is interesting then it will get popular and thus become a 'good' one. The defination of a good story is differemt for different people, but regardless of what type of story they want something that stamds out(wether that be in its art, storytellong or a unique plot or characters) always builds up interest. so to put it straight here are some things which you have to keep in mind while writing a story:
1) the initial plot has to be believable and appealing tonthe viewers, a good author considers what will be appealing to the majority of people.
2)the characters: most stories set common stereotype characters (like a a street thug) and break the stereotypes by having them do something unexpected(the street thug loves candies)
3)that brings us to STORYTELLING, whuch is probably a very vast topoc in itself, the story can become good or bad depending on how it is presented to the reader, most stories contain SURPRISE, SHOCK or something unusual that gets the reader inttested in the story, storytelling greatly varies depending on the type of story(comedic stories are told differently serious stories)
4)JOURNEY: or the pacing of the story. Readers like to read stories that are on to the point, not too long streched or too short, which leave the reader unsatisfied. The events that take place in a story have to make sense amd connect with each other, having some kind of 'goal' can help even an epidodic story.
Thats my perspective on a good story. I tend to prefer realistic art and characters with suspense, drama and overall completeness. So best of luck with your sory.
