>>11003258Kinda hard to answer because I'm spoiled by the size of my collection. Whenever I'm hit by a piece limitation I just pivot to a new idea. I do still run out of things or use my maximum, like with the brown floorboards and the dark gray tiles for the stone edges, but I don't really go out of my way to buy pieces for an idea I can't immediately build. My process is a mixture of random ludo and actually planning things out.
I usually start with a few isolated elements of the scene - for example here I started with the liquor cabinet and bar counter to get a sense of scale - and then progressively add elements to create a rough scene. I'll also make test builds of particular textures - like the trim around the walls made out of clips - so I can understand the dimensions and technique of how to incorporate them in advance. Once I get the sense of where everything goes I can stitch everything together into a final build. If I understand correctly I also suffer from not really knowing how big to make my platform until I've already made one, go "oh fuck, I should have made this a different size," and then rebuild it. Rebuilding is my favorite part about lego anyways so I just roll with it.
