Hi, My IGN is BananaTheBob and I'll be reviewing your plot today! :D
You are missing required elements!

I strongly suggest you clear your plot and start from scratch

/plot clear
then
/plot confirm

You are missing all of the required elements which are: Structure, Terrain, Trees/Organics
Additionally, the checkerboard patter gives me a headache if I look at it for to long (irl it actually does)

Suggestions on what to build:

Structure:
Try adding a structure with depth. This could mean a house or a castle or anything in between. Just be sure to add depth through creating multiple layers that are detailed with slabs, fence, stairs etc.

Terrain:
When adding the terrain, spread it through out the entire plot. Terrain is things like hills, mountains, cliffs etc. Additionally, make sure that it is smoothed to look as natural as possible.

Trees/Organics:
Bonemealed trees will not rank up. When you add your custom trees make sure that it is large and proportional. This means that the leaves can't be to big for the trunk and the trunk can't be to big for the leaves.

Good luck!
