Your readers won't notice. It isn't important for your story. Yet you keep making sure this little detail is done correctly just because you want it to. What is it?

I'm for example always making sure that my aliens have secondary emotional markers, like certain poses, or nostrils flaring up, or pupils widening, or the tail position. I'm sure people do not notice that or do not know the meaning it is supposed to convey, but I do them anyway.
And, of course, worldbuilding. I don't put even a tenth of it in the comic directly as a part of the dialogue or plot-related thread, but I always make sure that everything I'm drawing isn't contradicting it or is influenced by it.
