This is my first time drawing a PCB. I don't know if the design is reasonable. Please give me some advice.

The rationality of PCB is generally closely related to the schematic diagram, device placement and interface position input and output, and board function.

As for the basic direction and routing skills, if the same type of wire has different thicknesses, the routing should go straight instead of going around in circles.

The following is a random screenshot. Can the line be directly routed within the green circle? Are the lines in the green boxes of different thicknesses?

If you want it to be beautiful, you should pay attention to the spacing between parallel lines, and whether H3, H4, and TOF can be arranged neatly. Of course, these are not the main points.

There are a lot of dead copper. I need to deal with it. Either drill a hole or delete it.

Note, how many holes are there for the 4 fixings? Have you considered the size of the screw caps to provide enough safety clearance?

The one below is a 3.2mm hole, and the size of the cap is at the yellow line.

It is best if the lines here are equally spaced.

There are some places where dead copper can be discarded.

Well, it's nothing more than proficiency. You have to follow the basic principles and check yourself.
