Hi, Art

Nice piece of wrapping ... impressing !!!

Seriously, I do not see the unforgettable ceramic capacitor ( 0.1 - 0.22µ multilayer ) which ever should be placed CLOSEST as possible to the Pic supply pins ... ( lower and upper right )

Also, you should try to place the Xtal and its caps on the other side of the pic, close to the pic pins ... ( nice 8 Mhz emitter !!! ... lower right )

there's lots of noise to catch here ...

a big reservoir cap ( L.S.R. ) is also a must to place close to the multiplexed LED displays:
they generate lots of noise ...
