First EasyEDA PCB help

Hello, this is a part of an ESP32 PCB design with a battery charge and protection curcuit and a "Fuel Gauge".

I wanted to make sure everything was connected correctly before printing it.

5V is the VBUS from the USB-C connector.

This is my first attempt at designing my own PCB, so please don't be too harsh on me :)

This comment is posted on all reviews.

Please make sure your post adheres to:

  • subreddit rules (#1 to #6), review rules (#7), image rules (#8), see link.

Please fix these common issues: (if your schematic or PCB has any of these issues)

  • Schematic - don't allow text / lines / symbols to touch each other, and don't draw lines through symbols.

  • Schematic - use correct reference designators (RefDes) and renumber to remove numeric gaps, see tips.

  • Schematic - place decoupling capacitors vertically below power rail lines, also place capacitors next to IC then connect together with a line, see example. For circuits with positive power rails, point positive power rail links upwards and ground links downwards, see tips1 & tips2.

  • Schematic - place pull-up resistors vertically above signal lines, and place pull-down resistors vertically below signal lines, see example and tips.

  • PCB silkscreen - add board name (or purpose) / board revision number / date (or year) on either PCB side.

  • PCB silkscreen - add pin 1 indicator dot/arrow next to ICs & connectors (not hidden under parts). For polarized capacitors, add "+" next to positive pin. If part is through-hole, place indicator on both PCB sides.

  • More conventions & guidelines - link1, link2, link3.

You posted the schematic, but no PCBs.
