Is this a choice dictated by the art or by the artist? In other words, does the artist decide that characters in a particular comic HAVE to look very similar or does his/her style merely reflect in the character?
Personally speaking, I've not yet reached a stage where I can say I have a consistent grip of my characters or drawn enough of them to be confident either way, but I can say that many other comics I've read tend to have this innate feature or limitation (depending on the way you look at it).
At the same time, I've also seen some great comics with talented artists draw consistent looking characters who DON'T look blood-related.
Of course, this topic will apply only to comic writers who use human characters or at least predominantly human characters. Also this doesn't apply to Manga/Anime, where almost every other character looks the same to me...
