Bro I don't understand how you build such things in Hardcore, I struggle enough making that in creative, well done.
I play modded and have a decent world but all screenshots are pretty shite so won't send now.
What I taught myself with Hardcore is to stay as underleveled as possible. I had a Hardcore world of 3 years that I ditched cause I was completely overpowered, I had a fully functional automatic base with all the farms anyone could ever need, auto sorters, auto everything, so, I decided to re-do everything.
I got a nice seed from a random website of a ginormous island that I can make all my cool builds on over the months and years ( I don't like lands that span over thousands of blocks, so I specifically looked for a massive island ), got me a spot, and just started to build what I always wanted to build; a village with a shit load of stuff to look at.
I like to make stuff I actually use, like the church for example I specifically built to bury any pets that died, or just funny characters I named. And the farm fields are actually useful cause they give me emeralds; I don't want to automate anything anymore, it gives me a reason to get on my world and do stuff, and look forward to doing this or that.
Hardcore also just gives me a feeling of accomplishment; I didn't die once and made all of this in one life.
