First PCB design feedback

Hello,
I’m already a user of arduino and IOT devices but making a pcb is new for me.
I tried to make a small pcb for my IOT system.
It contains a ESP8266-01, DHT22, LDR (includes 10K resistor) and reset button.
Power supply = 9V with 2 voltage regulators: 5V and 3,3V

Is there somebody who wants to help me by checking my first PCB design and give me feedback?
