I painted the metallic areas on the wheels and frame in black and then painted silver over the top, thin enough to leave a thin strip of black as a shadow. It worked to good effect, given how much metal is on these monsters. I used Devlon Mud to blacken the ends of the brass colored barrels to give the appearance that they've been in heavy use. There's a ton of detail on these figures and such excellent molding give a painter the opportunity to shine. One day, I'm going to have to paint up a Venexia army.
Lastly, I want to share some photos that came to me from a blogger from Istanbul named Artar. Remember the line from the movie Crocodile Dundee when Paul Hogan is threatened by a tough guy with a switchblade? Paul says "That's not a knife!" and whips out his enormous Bush Knife and says "THIS is a knife!"
Paul Hogan looks over my Later Ottoman artillery and says "That's not Ottoman Heavy Artillery. THIS is Heavy Artillery!"
