Blimey, it's been a really long time yet again! Sadly no more progress on the Imperator. It's collected a frankly impressive amount of dust in a box. With the coming of Adeptus Titanicus, I'm greatly intrigued as to how the 'true scale' titans compare.
As I don't yet have the game, not to mention Reavers and Warhounds not being out yet, I've not really got a comparison, but I do plan to spruce up the titans I've painted and get a few more ready! The trick will be finding someone local to play.
Edit: Started pondering a new, more striking, scheme for the titans. I reckon black and orange - striped or chevrons, with white for honour markings/spot colour.
