I started with the interior and painted up the pilots to match the uniform of the engineer who was unfortunate enough to be entombed in the torso section, but gave the Princep a bit of gold flourish. The interiors were actually one of the harder parts to paint - loads of fine detail but access was a little tricky.
All the control panels were painted up and the interior of the roof was also painted to match.
Being Legio Mortis I took a look at some pictures and was pleased to see the heads are typically red, which breaks up all of the black and metallics nicely.
Looks pretty nice all built up!
