You could bring the traces between diode bridge and main filter cap closer together, to reduce loop area, and that would also allow a smt cap/lands to be placed close to the diode bridge if needed due to diode reverse recovery.

You should try and take R2 from the input cap terminal pad, not from R1 pad.

Regulator outputs typically use a star ground at the output filter cap, whereas you have connected reg 0V to a trace halfway between input and output caps.

Why are the 48V terminals at opposite ends ?
