Custom Keyboard PCB

Hello everyone,

I just finished making a custom keyboard PCB in KiCad as my first ever project (design credit to @Exercising Ingenuity, YouTube, and I adapted it to PCB). It's quite a simple piece of circuitry--just 44 tactile switches, 44 diodes, and a Waveshare RP2040-Zero. However, I have very little experience with circuit design, and I don't want to order this PCB only to discover a tiny error that messes up the whole thing. Could someone with some experience in these matters look it over for me, and see if you can spot a wonky design choice or outright screw-up?

Thanks in advance; I've been thrashing all 3 of my brain cells trying to design this thing correctly.
