Need an oil change Sir?

I've been decorating The Omniscion with the servoskulls - and it added just the right amount of extra tech I felt was needed. I think I'm about there where I only need the last few touch-ups on the base, then I'm actually done.
A small teaser:

Skulls

One of the most iconic images and my absolute favourite critters of the 40K universe are servoskulls. For as long as I can remember I've always found them incredible cool, with just a hint of DarkTech and spookiness.
Finally I found a good reason to paint up some.
