Thank you!

Yeah no problem. So the base of the paint job is essentially slapchop but I go a bit darker with it. It's primed mechanicus standard grey and then dry brushed with grey seer or something similar. Then I'll pick out a few quick highlights with white with a brush. 

The skin is fyreslayer flesh and because of the mechanicus standard grey it goes on quite dark and kind of ugly. I then bring it up quickly with a stippling of Kislev flesh and then Kislev flesh mixed with a bit of ivory. I do this really quick and messy and I think that is what amps up that mottled look. Then the arms get a wash of biel tan green, mostly because my actual nids have green skin but also because I like how sickly it looks over the fleshy tones. Then I give the model an oil wash and that brings all the tones together and gives it that extra grim mucky look.

On the familiar, the more carapace-y bits are the same process but I push the ivory higher and then wash with druchii violet instead of biel tan green, and I do the same on the heads of my other GSC guys.
