My two cents would be to use thicker traces, in this application using the thin traces doesn’t help, and can make them easier to break. I would personally add ground fills on top and bottom out of habit mostly though, not sure if it would help in this situation.
Also use the silkscreen, it’s free (effectively) so put labels on connections and also you can import images into it if you want (enjoy it).
(Note I’m on mobile so can’t inspect the kicad but will if I remember later)
Edit: sorry didn’t see flood fills I’m image. Ignore that 😅
