Very low-power ESP8266-based motion detector

I'm building a new schematic to set up an ESP8266 m-based motion detector which should only work during the night.

My goals are:

  • Use an RTC to store time and read time when ESP starts up (if not in time window, it will go back to sleep).
  • The ESP8266 will be coded to disable WiFi on boot to speed up the boot process, and to limit battery drain
  • The ESP8266 will only connect to WiFi when within the time window to send a signal to MQTT

I've made multiple schematics and PCBs already, but the trial-and-error is starting to cost a lost of money, so I'd like some experts to review of my schematic.

The schematics can be found here: https://we.tl/t-JaEAZL9Poa

In case some folks want to see the schematics directly, here they are:

Combined view of the schematic

For the expects amongst you, would you bother taking a quick look and based on your experience tell me if there are any major issues? Especially with focus on the latching circuit and the boot high/low interference I may occur when the ESP starts up that may compromise my complete schematic.
