This is my second attempt to design a board with microcontroller chips. From my last question, I learnt a lot and this design has improved from my last one, I believe.
Once again, what can be some possible improvements in this schematic design?
UPDATE 1:
I tried to solve the issues that you figured out, let me know if my changes are correct and what other things need to be resolved

I'll compile a list here.
No bypass/bulk caps at all on regulator input
CH340 power supply connections are not correct for 3.3V VCC operation
Pushbutton pull-up is useless, as DTR# is output
Pushbutton will short DTR# output to ground if pushed
LEDs likely prevent UART receive from working at proper voltage levels
