Nice! My 2 cents:
Would the extra resistors for the LEDs fit on the PCB? Maybe somebody wants to use them, so they may be a good addition. At least adding only a soldering pad next to pins 6 and 10 of each PIC, without resistors, so one can add the resistors and LEDs if needed. Just a thought...
Then, looking at your PCB vs the schematics, I see you have connected pin 6 of the PICs to J2 (SV6 on your PCB). As far as I see, Pin 6 should be the "Power ON" LED, and pin 7 is the one that should go to J2. Am I wrong?
