i suggest minecraft skin contest. :D

how bout a map that has every natural structure spawned upside down, like trees, villages, woodland mansions, mountains, etc. I haven't seen almost any upside down maps and I think it would be very interesting

As a community (build) challenge/contest/event lover something along the lines of:
"terraform contest inside a goldfish bowl" to keep it simple/accessible.

You seem the perfect person to judge it, possibly get some new fresh idea's for future maps for yourself.

As a possible step 2, collect those and place them inside a special world as shrines (or something) to discover?

Create 1000 worlds - 1 for each subskriber :)))
Okay I'm joking :'D
I'm really digging Yuki's idea of something like a special map with a specific shape (Such as a heart) or something to represent yourself. Maybe a terrain that (When looked at in WorldPainter) is your minecraft skin-face - Thus someone can play Minecraft... On your face! :D

Combine most of your worlds into one giant Minecraft world.

maybe a party in hypixel or the pmc server
i usually play on hypixel sumo and win some noobs i eventually find, and lose to most players ._.

Maybe a big map in the shape of something? Or maybe (big project) a world with 1000 small builds?

a 1000x1000 map that has a block of dirt in the sky at the very center because why not

A contest?
Map or skin or other contests?

plane crash map maybe idk, also your almost level 69

1k x 1k heart shaped map would be neat, small compared to your normal stuff but a neat way of saying thank you too.

for 1000 subs you throw a Blip Appreciation Party? BAP
No um really, how about an in-game event or maybe a contest?
