Remove the copper fill under your ESP-01 ANTENNA
Your Via's are too small 16mil? Unnecessarily small I would not go below 1mm= 40mil
Why are you placing parts on both sides of the board, you have plenty of real estate that is unused?
Your 5V regulator doesn't have any bypass caps, at least a 10uf on input and 100nf on output.
Your 3.3reg is only powered from VUSB, so the ESP01 only works when the USB cable is plugged in?
My two cents.
