STM32F107RBT6 + LAN8720A custom board.

I've drawn my own schematic that uses the STM32F107RBT6 and LAN8720A chip.
And this is not an work on company, not related with my job. just hobby.

I made this to study firmware development in order to make toys that utilize Ethernet.
and I ordered sample boards to PCB factory.

It's very sloppy because I didn't learn electronics from somewhere and just tried it on my own little by little.
I'm even writing this post because I want to ask something, but I don't even know what to ask.

I would like to get a full schematic review or advice. I know the schematic itself works, but I also know that it doesn't do everything. If engineer were to read this, it would probably look very sloppy, but I would still like to hear from them.

This drawn using `Kicad 8`, available on my github repository.
