So imported my Bishop and realised at some point it got a bit messed up on the bottom 
Anyway fixed that then chose slightly different features on the queen to follow than Michael did.
Quite happy with it so far. The crown took a couple of tries to get right - especially removing parts of the crown by scale-snapping. Still not sure if I’m doing that quite right… seemed quite cumbersome.
Also instead of recreating the bobble I didn’t delete it, just repositioned it.
