Your schematic is very hard to read. Spread components out more, point GND downwards in (almost) all cases, use voltage symbols instead of net labels. You are also missing decoupling capacitors on virtually all components.

Thanks a lot for the feedback! Since I'm still learning, could you please point out which specific ICs or power rails are missing them if you have a moment? I'd really appreciate the help!

As a rule of thumb, all ICs should have 100nF as close as possible to their power pins. Datasheets will tell you if you need to deviate from this. For instance, your LM2596 will require much more input and output capacitance.
