This layout would be good, if all the different supply voltages were totally separated. But mostly they aren't. If they come from the same power supply unit, then some capacitive coupling will exist, resulting in a certain ground loop for high frequent digital currents.
Again, I would suggest you to use the scheme I posted in my last reply. Connect all the individual grounds at this certain single ground point. Do also connect the chassis ground to it.
And if you must cross the separated ground planes, then don't forget to introduce a series impedance, where the signal traverses the gap. Otherwise you connect the both ground planes together again at this point via stray capacitance and introduce a ground loop for digital ground return currents...
