Oh yes, so much green stuff. I'm seeing green at this point.
But sure! Most of it was just mad sciencing models+bits+green stuff together. The McM crew is for the most part out of the box with minor mods/fancy bases, but I did a little more work on a few. Like the Malifaux nurse. I amputated her legs and repositioned them to perch on the edge of a plasticard built table with some zombie bits and green stuff as a half dissected corpse. Bases, tables, pipes, etc are all made from Plasticard rods and sheet, though I have some of Wyrd's Morgue bases mixed in too. The dog is an old school D&D Chainmail skeletal dog with some greenstuff fleshy bits, and the other nurse.... I actually don't know what she's from. I got her, sans her head from a friend of mine, gave her a new head and used her for my second nurse. The Rogue Necromancy was, at one time, an Avatars of War cerebus, but after some serious GS surgery and the addition of GW Chaos Spawn bits, is one no longer. The avatars are completely from scratch, save for a few zombie arms here and there.
Any other questions you have, I'll be glad to try and answer. I don't claim to be any sort of pro, just a deranged hobbyist, but I could probably give pointers.
I think that's the great thing about Malifaux-- it's a Skirmish game so you can put a lot of individual effort into each model and not have it get overlooked among a hundred others.
