Generally speaking, in circuit design you need to understand that "normal" BJT transistors are fundamentally different from Mosfets. Transistors amplify based on the current at the base, while mosfets regulate almost exclusively based on the voltage supplied to their gate. You can fully open a Mosfet with a few microamps, provided the voltage is as high as the drain, although it starts to work only at about 3 VDC and has a similar voltage drop.
Also always place the inductive load before an NPN part, but after an PNP. (else it doesn't work at all)
Even tho I'm a rookie, these things helped me a lot.
