Review my 3 layer PCB design

I have created a 99mm x 99mm prototype circuit board stack which I need reviewed for errors by a skilled freelancer with an understanding of electronics, able to understand datasheets and the electronics used.

The PCB is an LED light engine which has the following electronics:

5 LM3414 1A LED Drivers

30x High Power LED’s

1x LM7812 Linear Voltage Regulator

1x LM2672 Switching Voltage Regulator

1x ESP12

You will need to review the circuit design, ensure that they agree with the respective datasheets and will work as intended and provide feedback / fixes.
