This is my first time using a schematic or PCB editor and would like some feedback before submitting the order.  This is not for production, but rather just for me to learn how to go from a breadboard to a PCB.


Notes:
- Track widths are .3 mm\, except some + and - connections at .6 mm
- P2 is for future expansion.  I don't know what I'll use it for yet.  Maybe a distance sensor.
- P3 is to drive a 5v WS2812 LED ring.  Max is .72 amps if using white at full brightness. More likely to be half that or less.
- Two layers


Some questions I have:
- Is this a reasonable ground plane?
- Are my track widths reasonable?
- I have two tracks at the top (one on each side of the board) that seem a little wonky. Is there a better way to do this?
