Weirdboy isn't a good HQ.
Nobz need a Painboy and cyborg bodies
Drop the rokkits from the Boyz as you're going 18" and not shooting. Only time it's good is when you're out the transport but a single rokkit doesn't have great chances and 12 Orks don't last long outside a transport either. So you should increase troop numbers, 36 Orks for troops isn't a lot.
You could take a Wagon as dedicated support for the Nobz
