Look great.  My only comments are on the RST line.  You may want to include an
R/C pair on the reset line to ensure that the device timing is met for the
reset signals.  Something like below, pardon the crappy ascii art.  

                 |------> To chips
    V+           |
    0---/\/\/\---*---|(----*----O GND
                 |         |
                 |--o   o--|
                       /
                      /
