Exposition; there is the rub, though in the absence of a question.
Just how much is too much? That is the actual question.
I have seen this discussed, weighted, challenged and justified over and over on various groups and fora; it is called info-dumping, the Wall of Text...it is called many things and much advice about avoiding it to be found but none seem to answer the most important question for the apprentice author, for the journeyperson; how does one avoid doing it?
It is easy to do - I raise my hand in guilty associatin, I have done it - to be in the heat and passion of a scene, and to go off in detail about the background to a particular event, place, relationship, etc. It is likely that you have spent a lot of time, effort, and heart in creating your world and are justifiably proud of it, I know I am. You want to show how great it is to your readers and have them enjoy it as much as you do, I completely understand. I still have this awful habit at the moment of steering unrelated conversations to my writing, or dropping anecdotes about characters into relevent situations, it is causing both friends and family to "assume the expression" with me often.
Admit it; you know which expression I am referring to!
You are in love with your world, it's like your child because you created it, you nurtured its early stages, you developed and taught it tricks and gave it direction. It is a part of you and you are right to be proud about that. Thing is, not everyone sees it that way.
Somebody giving one of my artworks a like does not know that it took anywhere between 3 hours and 3 days to create that, to tease and massage it into an acceptable shape. In fact a large proportion of viewers will not even see the finer details I agonised for hours over getting just right. But it looks pretty and conveys a feeling or three, so they click a button and move on, maybe even pass a moment held in its grip.
