New Design

Hello guys!
I am new to schematics and PCB designing. I have recently tried designing a schematic but, I am not sure whether this design would work or not.
Can you guys help me find out mistakes in this particular design.

No a detailed review but here are some remarks.
1) Put power (+) to the top and Gnd to the bottom.
2) Do not place the Gnd symbol up-side-down.
3) There is no need for the opto-couplers in the output. 1k from a 3V3 device to the base of the transistor to drive the relay.
4) Add some descriptive texts to state what that section does. Ie. https://www.youtube.com/shorts/OsM8lG-tR3A
5) Try to have inputs on the left and outputs to the right.

We have just attached four header pins to the input part that, I can manage. What I really need to know is that, can I put this design into final production. Will it work. I am not able to rectify it.

@Chirag950 is there a specific area or specific connection where you think may be a problem or you have concerns about?

With due respect, I am worried about the Ethernet working with esp32. The main concern in the schematic is whether the Ethernet design would work fine or not? If not, what changes do I have to make.

If you are not sure about Ethernet, I would recommend to find and existing development board with the connection you need and do exactly the same on your board.
