Update - Aquila Strong Point

Sated with Turkey, glutted with pie, but forced to go back to work (*5 days a week, no less!), I've managed to get a little hobby done and advance my Aquila Strong Point Project.

As you can see, I've done the first part of the drybrushing for this - an underlayer of Tin Bitz, and then Shining Gold and Leadbelcher (*which I think used to be called Boltgun Metal).

From here, I'll give it a thorough wash, and then some overbrushing.  And then it's on to the blue and white to give it an Ultramarines feel. 

For now I've painted the barrel of the macro cannon in metallics, but I am leaning towards repainting its mount in blue

But what color to paint the missiles?
