Why destroy a good build with ugly parkour? A red bed? A huge green cactus? Blue floating water? Polished andesite? I think the parkour could have been done so much better and look nicer, right now it feels ugly and pretty random
Nice addition to the thread acid, I see you take this very seriously. It's good for you to give such a necessary and important comment on this important post.
The easiest way to find themes is by being a gamer. If you play any other games look for a good theme in them. It can be a character, enemy, object or location.
Some other easy way to figure out a theme is memes, album covers or real life locations.
