[LVL ED] How do you make a well detailed level?

[Putmalk]

You made one of the best detailed mansion I've ever seen in my life, I only I can do it like yours but that's just copying. sigh, i'm out o ideas, I wish I had one just like you.

Feel free to do something similar, i dont care. You can only learn by doing. How do you think i learned?

I may record more 30-minute timelapses (thats how long it took to record it) if people find interest in them.
