Really pleased people are enjoying these, as is probably obvious I'm having a lot of fun making these guys, hence the frenetic activity! The new Mechanicus kits really are wonderful with all sorts of conversion possibilities, and I think there's a lot of scope to branch out from the generic "robed guy with servo arms" look to do all sorts of weird and wonderful things. I haven't even had a chance to read the Skitarii codex yet; bet there's heaps of inspiration in there, let alone when the main Codex turns up.
@Battybatbats, Your noblewoman was actually the thing that inspired me! My original plan was to do the oracle's seneschal as optimised for diplomatic contact, ie less intentionally creepy to normal humans, but when I saw your use of the Coven Throne handmaiden legs, I had a sudden flash of inspiration and realised I could do a M.30 Martian version of this. She'll be a bit less grimdark than yours- I'm intending to go more for the Fritz Lang Metropolis look- but I'm still waiting on bits, and these things evolve so who knows?

So anyhow, here's some progress on the Eremech. He's still WIP, but he's getting there! He'll be tripod based like the others, but his legs are prehensile; the remaining limb will be doing hand duty, petting a friendly servo skull. His cog (which came from here, btw) has now been accesorised with a skull, which is one of the Scyllax heads trimmed back; that kit really is invaluable to anyone doing anything Mars-related. His torso is a cut down bit from the Necron Command barge.
@KrautScientist, your chap was definitely an influence; I did a search for Cairn Wraith conversions for ideas to steal inspiration before I embarked on the Eremech, and while I didn't want to go as gribbly as Legion (this guy is actually perfectly benevolent, if a bit funny-looking), as you can see below I borrowed the tentacle torso concept.
What else have been up to? Well, I've painted up a first go at a Martian-themed base. It's not dusty enough yet- I need to find some weathering powder that's the right colour- but I think it looks sufficiently Martian while at the same time allowing me the freedom to use crimson on some of the pilgrims, should I want to.

And finally, I've made a new pilgrim for the group. This guy is a Scrivener, despatched from a distant Forgeworld to consult the Oracle on a matter of legal dispute. He's clearly had a hard journey; of his constellation of eight servo-skulls, he only has three left. Presumably the other five have been sold along the way to pay for passage.

It's funny how sometimes the background for a model comes first, and sometimes the model just spontaneously appears in your hands fully-formed; this little chap naturally emerged over the course of about ten minutes!
