Default Input selector board with LCD/IR and motorized pot

I've been building this PCB based on Muffsy relay input selector. I had added some optionals such as IR receiver, switch encoder, motorized potentiometer, LCD screen and an ethernet module (just in case). I replaced the NodeMCU for an arduino nano since it doesn't have build in wifi to interfere with internal components since im placing this with a preamp+amp and it has more available pins.

Recommendations/critics are well received

disclaimer: this is my first pcb modification and first time I work with Eagle files.
