So, I devoted all of this weekend's hobby time to the Knight, who is certainly deserving of a name, as soon as I think of one. Here's my progress so far.
Don't let the armour plates fool you; they're held in place with Blu-tack. Only the one covering the top of the head has been deemed sufficiently complete to be glued into place. As for the others, there's a lot more to be done.
Here's a closer look at the carapace. I'm paying extra close attention to this, seeing as it's the most visible part. After I line highlight all the red with some Trollslayer Orange, I can start applying decals.
The little green window was done by painting successively smaller crescents of Dark Angel Green, Warboss Green and Scorpion Green in the lower right corner, followed by a dot of white in the upper right corner. Note that the transition between Dark Angel Green and Warboss Green is quite large, so that took a little blending.
The Cog Mechanicum's white bits were done in Ulthuan Grey, followed by a wash of Nuln Oil, then layering again with Ulthuan Grey. I line highlighted with a little Ceramite White on the edges. The black bits are just black with line highlights of Codex Grey. The brassy bits in between are simply Dwarf Bronze washed with Devlan Mud.
All the rivets were washed with Nuln Oil then highlighted with a dot of Ironbreaker. Tedious, but I kind of like the effect.
Doing the chainsword's stripes as black on yellow was definitely easier, as I didn't have to worry too much when applying the coats of Iyanden Darksun necessary to achieve a solid yellow. After that, it was a simple matter to pick out the stripes, then brighten the yellow with Golden Yellow.
The armour plates are all going to be blacklined with Nuln Oil, then line highlighted. A pretty arduous process, but I think it'll be worth it. Here's a closer look comparing two armour plates, before and after blacklining:
Anyhoo, after the detail work is done, decals! After that, final touch-ups and we're ready for WAR!
