Mosfet motor driver

So I needed a motor driver because the arduino motor shield I am using cant handle the power needed. The lamp represents the motor. The 5v signals would be coming from the motor shield. Did I miss anything?

you can replace two 4.7MΩ resistors with one 10kΩ

what are the top fets for? don't need those to drive fet gates

the high side drivers will need to be bootstrapped, the gates will need to be around 32V to fully turn on. otherwise the fet will burn the power up as heat

opamps can be replaced with transistors easily

actually if you're driving silly amounts of power with only occasional switching it might be much easier to use relays instead

Relays would be to slow for incrament accuracy and i was thinking would cost more in power. ill change out feeding with transistors.
