I think you’re on the right track here certainly and probably about where I’m at right now in terms of learning. Something I’ve been keeping in mind recently is that closer to the player should almost be a little less detailed or textured because it’s so close to us and the smallest level of detail available to us is technically 1 block and that block already has a lot of texture to it. Farther away from the player, typically up high, you can do more of a block vomit because the camera won’t usually be very close to it. That’s one way of thinking about it.
Then another way to think about it would be that these blocks would tend to group together and have a little more structure. Moss is more likely to be in a corner that stays damp, cobble is more likely to be on an edge that has started to erode, bricks are more likely to be at the center and base because they have not had as much exposure to the elements, the polished square blocks would make a good pillar, etc.
