Hello!!
I have been spending almost a month trying to recreate this image for myself. Some things were easier to get than others. All of the ores were pretty simple though I did have to mine a little more and specifically go out of my way for coal. I also had to start a cow and sugar cane farm for the beef and books. I had to run to an unexplored woodland mansion for the totems and the vex armor trim. And I had to travel to unexplored bastion remnants for the smithing template upgrade. I also had to mine for netherite for the first time.
You may notice that my armor trims are different. That's because I just like these ones :) but it was a pain to get because I had to find armor trims from unexplored strongholds, as well as finding one from desert temples which was way harder than it was supposed to be because I had to explore like 6 before I found one (and it also had a miku apple in it so like yippee!!)
I also had to make a lot of villagers because I wanted my armor and tools to be perfect before upgrading them to netherite. I heard enchanting them is more expensive in netherite, though I haven't fact checked that.
Overall, this was a very fun challenge! While this screenshot certainly isn't all the materials I own, it is nice to display the hard work I had to go through to obtain these items.
Thank you TJelle. Hope to see you on the server some time <3
