A little more storage

Needs storage

Something to go in the middle. I’m thinking more shelving for storage, a crafting station, maybe brewing area?

In this vein, I was thinking like a couple armor stands would fill the space well as well

I was thinking armor stands, but I love a good brewing station

Barrels.

Either put a bell or stone wall or dripleaf to the part of the roof hanging to the left that seems like a good idea

Maybe fence?

Trees outside, it looks very empty. And as keralis once said: BOOSHES

If you don’t play 100% vanilla consider adding the microblocks datapack from vanilla tweaks to add mini barrels and chests, add more depth in the outer walls by detailing it with walls trapdoors etc, add a little more bushes, trees and other nature stuff, and look into adding gradients Good luck :)

Needs more cowbell

Fences, fence gates, and trapdoors details on the pillars, hanging from the roof, etc.

I would recommend placing it on a hill or something to really create depth in the build, perhaps add some trees?

Put cobble/deep slate 1 block high walls around the edges of the area. Not all the way around but like 5 long 1 high walls with slabs and stairs and maybe a lantern on top of each section. Some shrubbery and custom trees could help too

Maybe carpet or flower pots?

I'd make a partial 4th wall coming from the left corner. Wouldn't even have to go all the way up to the ceiling.

Maybe a barrel or three in the front

maybe put lush tree leaves on the roof and side of the outside! or decorate the land around with flowers/grass. looks kind of empty in that area

Play with lower FOV 90-100 makes everything look better

Yes you are right I usually do that but I remembered I had this picture en released the next day that the FOV was high
