Looks much better than a typical beginner, congrats. As someone with a bit of experience (and a degree) I'd just suggest that you avoid breaking up the ground plane so much. It's the single most important rule for PCB design. Traces on that side should only be short links to jump around a trace on the top side, where possible. It matters the most for SMPS, RF, etc.
Appreciate the feedback! I was having a hard time finding anyone with design experience in my social circle, so I mostly relied on asking Claude if something was or wasn't conventional. I did try to keep my ground pour free of bottle-necks.
