I think this is okay under current rules, didn't want to do a thread per mini.
Here's Pandoras crew all primed and based on some cork:-
Next I basecoated their skin, since they're all ghosts (I think) and I needed 1 colour to tie them all together, I used Vampiric Shadow on all of them:-
And then I basecoated the smoky, twisty lower halves of the Poltergeist and the Woes with a 3:1 mix of Vallejo Hexed Lichen/Nightmare Black:-
I also meant to paint the strand of smoke from Pandoras Box of Mystery the same colour, but I forgot.
