Sky Dreamers : rules to build your structure

This map is a build tool for my Sky Dreamers project. It's not a playable map.

Brief

The project is some kind of SkyBlock map for Java Edition: you start in a void dimension with no resource and you have to farm to get them in the overworld. But one of the specificity of the map is to only brings players to the overworld at night. If they survive the night, they will be TP back to the floating island dimension when the sun rises. And of course, they keep their inventory/resources.

As a builder, you have to build a spawn for up to 8 players. The spawn will be loaded randomly at the begining of the adventure.
As this is a realm of dream, the spawn can be anything, any theme. So, you can build whatever you want. A giant crystal with fontains, school bus riding a rainbow, a floating fisherman's boat, an upside-down prison from WalkingDead, your personal room with x4 ratio... It's up to you!

How to join?

Download this map and play it with Minecraft 1.20.4.
You will spawn in a structure block cube: this is your maximum build size.
Build whatever you want and send it to me.

Generic rules

- Theme is free.
- Your structure MUST fit the 48x48x48 max size for structure_block.
- Prefer smaller build as it is a "skyblock style": player should feel the danger of the void.

You MUST

- Have a build that is easy to walk on, at least 8x8 walkable area. This is a starting base, players will spawn on it with no equiment.
- Define 1 safe spawn area: an empty 1x2x1 air space, with bedrock under feet. Player will spawn, and respawn here. It does not have to be at the center, place it wherever you want.
- Place 2-8 beds with safe space nearby: those are paths to the overworld at night.
- Place your player_skull somewhere, as a credit feature.
- Avoid utility blocks like crafting_table, furnace, chest, etc... The player has to craft them himself.
- Avoid Lava and Water block. But you can use lava OR water.
- No beacon, or OP block, obviously.
- Do not use entity or block that player cannot break or modify (ex: item_display, block_display or locked armor_stand)

You SHOULD

- Avoid resource blocks like iron_block, diamond_ore or other "rare" materials that may break the survival.
- Suggest players to use your empty designed spaces (at least at the begining of the adventure). They will probably rebuild everything later.
- Include some lights in darkest areas (mobs do not spawn in this dimension).

Additionnal infos

- Your build will "float" in the void. Starting at 0 220 0. 20 blocks above clouds.
- This is a safe area. Only custom mobs might spawn. You can include lights.
- Grass, leaves and water are colorized by a biome color that changes over time. Default: purple (red, yellow, blue, lime, aqua, pink...). You probably don't want to make vegetation as your main style.
- Don't try to give specific resources to players, they are supposed to go to the overworld for that. Just build as you want.

Job's done?

Zip your entire world, and send it to me on Discord, I will carry the "structure" part (Or send me directly your structure.nbt if you know how this works).
Don't forget to send me your Minecraf Nickname, your country, and your title for your build.
Keep in mind that I won't be able to include all the maps in the project (I'll try to). I also may replace some blocks to fit the final experience.
You can submit up to 3 builds.

About credits

Your build is your property. Participating to the build event, you allow me (FunkyToc) to add it in the global project named "Sky Dreamers".
Your Minecraft nickname and your build title will appear in a credits.txt in the final map folder, and also on the main project PMC web page.
You nickname is tell when starting a new adventure with your spawn-base (see screenshot below).
If any of the previous "credits rules" makes you incomfortable or if you don't want your build to be added to the project, please, send me a message about it.

Don't worry if some rules aren't clear, I will check it anyway :)
If you have any question, please, PM on Discord.
Thank you for your time, I know it is a very limited thing.
