hiThanks for the help! I tried to make all the corrections. Modified version (font is enlarged, connectors are displaced, dimensions of tracks and vias are enlarged, cleaned up blank areas).

Isolated copper pours may tend to couple circuits that may not benefit from capacitive coupling. In fact, I am wondering about the benefit of copper pour, if there is any benefit at all. It does add weight and value, so it may not be beneficial.The connectors don't have a pin 1 marked. The ESP32 doesn;t have pin 1 marked. It could even be a square corner on the rectangle.
the connector silk screens makes it easy to be able to insert the connectors 180 degrees. There are likely features on the connector.

+1 on this observation.I do see one place where the common connection is floating, which is towards the bottom left corner of the upper image. It is not totally isolated but only one skinny strip connects it.
