P-N CH Mosfet H-Bridge

High Amp MOSFET H-BRIDGE self-design.  The 1 ohm resistors and lamp represent the motor.  Still working to finalize the parameters for the FQP30N06L & FQP27P06 MOSFETS, & NPN PN2222A Transistors.  Any help is greatly appreciated!
UPDATES:
(1) Added PC123 opto-isolation represented by transistors in upper corners.  Switches at each side represent Arduino Pins. 8V is separate power supply (Buck off 12V).
(2) Reduced R values 10X to bring currents from uA to mA range to minimize noise issues.  Added 220ohm for PC123 (The R 10K doesn't exist with the PC123.  Internal R is ~60ohms equiv giving 20mA).
(3) Add LED's for each power line.
