anyways, to answer the question, i think my worldbuilding and characters are the best things.
though a lot of my fav worldbuilding in my world wont actually be featured in the comic, aha (like the continent Cavrah's cultures are the most developed and my fav, but we wont even be visiting that continent in the comic). ive had this world for very long time (with some aspects being improved and revamped stuff from even elementary school!) and its been my passion project for years. a lot of worldbuilding. even get obsessive with things that probably will never show up - like making the tectonic history in gplates, and then naming every major landform during that process, lmao.
i also like my characters - i think character writing is one of my strengths, but who knows! maybe im completely wrong. but characters and worldbuilding (or utilizing the real world well, if its set irl) are my two main focuses in stories - not just mine, i mean, but ones i consume - so i care a lot about putting work into my characters. consistent motivations, making their choices realistic to who they are, showing how they developed into the characters they are, etc.
