Nice keyboard! I'll approve it this time but know that in the future you will have to have a .step file for the cad. If you do not, it will be rejected.

Your project looks great! Just one last thing - please include the shipping option you've chosen, so we can verify you chose the cheapest one! (Usually global standard direct line)

A final 3d render with switches and keycaps are needed.
In addition, your KiCAD .sch and .pcb files are needed.
Finally, please provide the GERBER files in a .zip format.
Other than that, great job!

ZMK config

QMK doesnt support wireless splits so I decided to use zmk. There is some learning but the docs are great as mention in @koeg 's tutorial. Here's the keymap.

I didnt worry too much about this step since I can reprint myself if needed.

Minor PCB changes

Had some DRC problems, also forgot to switch to THT diodes on one side so I had to add and wire them. Other than that I did some silkscreen changes, and now the pcbs are ready.

Right Side of PCB

This was simple but tedious, same thing just different wiring. I also changed the octopus positioning so it wouldnt just be an exact copy of the left side.

PCB Left side routing

This took so long especially since I was afraid to use vias at first idk why.
I also did the footprints and everything, made staggered columns, and placed the thumb keys.

I also added some images to fit the theme.

Picking parts + Schematic

Finally got around to this project since it's winter break. The plan is to do a corne but with my own twist. Wireless, no connection between the 2 so I will have to use ZMK.
I'll use a NRF52840 board, kailh choc v1 switches(no hotswap though), hopefully some nice keycaps if possible, a 3.7V LiPo and of course diodes.

Now it's time for the schematic.
I loosely followed the guide but heres what I came up with.

I decided to add a 0.91" OLED and a reset button.
