Is this a double sided board?

I'd add a bypass cap (100nf) between Vcc and Vss pins
of the 876.  

I often use a 100nf cap between the output of the
regulator and ground.  Supposedly prevents
oscillation.  check the datasheet for your regulator.

I assume x1 is a resonator - probably a good idea to
not run any other traces near it.  I always try to get
as much ground copper around the crystal/resonator
pins.

You could probably make this a single sided board.

What design software are you using?
