My first board (Arduino Pro Mini Shield for RFM69)

[user2684]

I'm very new to Kicad and PCB design so I'd be very grateful if anybody has any thought, comment, suggestion, etc. to share regarding my first board. I'm sharing the entire kicad project at https://www.openhardware.io/view/605/Arduino-Pro-Mini-Shield-for-RFM69.
Even something such as best practice/naming convention, etc. which may sound trivial for an experienced designer could be helpful for a beginner like me :)
Thanks!
