Did I design this right?

[KrisDong]

Hello, I've been working on designing a custom PCB for a custom mech keyboard, and I have no clue if I did it right. I have zero experience doing anything like this, and worked following a guide online mostly. Did I wire it correctly, even if it is messy? Did I do some really big mistake? Here are schematics and pictures, and I'll figure out a way to upload my KiCad files here, if that's allowed: https://imgur.com/a/TpA6d64

KiCad Files!

Hi,

I don't work with the KiCad, so I checked the images. Try to use a solid polygon for a ground plan instead of routing ground tracks for all components. This is the first tip before anything else
