I'm currently writing my first graphic novel/comic and am wondering when people feel SFX should be added. I know it probably depends on the tone of the story (for reference mine leans on the more serious side, a sci-fi civil war story). I know for myself I intend to limit them mainly to combat scenes.
Some comics like The Walking Dead seem to have SFX for every action in combat scenes, from explosions to gunshots, where as others such as Marvel's X-Men don't. Just flipping through X-Men 8-10, many actions such as slashing of swords and explosions had no SFX whatsoever, while others did, which kind of confuses me.
So this leaves me with the question of when should I add them? Are there some cases such as a particularly significant explosion when no SFX should be added? What's the general rule, if any?
Any advice and thoughts on this topic are much appreciated, thanks :)
