all of the names are good in different ways, but it depends on your preference. kanovia is definitely the one that stands out the most, though! and if you're worried about it, there's probably going to be a bunch of people naming their islands stuff like paradise and palm bay. even if you go with romaki's recommendation of novia bay, that's still more distinct since it has something thats reminiscient of a word but isn't, like, an actual english language word. those sort of names always stick out more to me, even if i prefer to name my towns after types of flowers myself!
