Without better photos it's hard to really see anything. Based off of those it looks just fine.

Grab a digital multimeter, set it to continuity check (audible beep) and check for continuity between gate, drain, and source legs of all mosfets. Keep in mind that occasionally there will be a beep that will go away after a few seconds. That's normal as you're charging a cap somewhere in the circuit.

Smoking usually indicates a power supply fault so it's best to check there.

Also don't freak out when the rectifier diodes show continuity, that's normal.
