There's the guy, painted. There are a few areas that need another go over, but largely, Vulkan's table top ready. He's painted in typical Salamander colors -- or at least their equivalent -- as far as the green and lighter green highlighting. The back pack I left understated. Yes, it's covered with bones and skulls, but leaving it black with a dark gray highlightwill marry the miniature to a larger Salamander force while still setting him apart. I also came down on the side of "fluff": Yes, the Salamanders make great artificer armor, but they've also got a humble streak in them.
He'Stan's pic in the New Marine Codex shows a nice piece of artwork on his left shin-plate. On that small of a space, and with my eyes, that's a stretch, but I did pull it off somewhat in miniature, pictured below.
The inside of the cape: I went away from the tanned leather look and did a few decorative lines and some hammer symbols. The spear's shaft was done with GW's "Tin Bitz", but to me it looked like mahogany or some rich wood. Maybe if it were decorative only... So making a bunch of tiny letter "S"'s with a copper paint hopefully gives it a more metallic look. I left the blade itself plain white. It's stated to burn white hot and with the overall darkness of the rest of the model, I like the way it stands out.
I know, the crossed hammers look a little lame and I'll fix them. But for the 3+ Invulnerable save giving mantle, I painted it a darker green then dry brushed it with a metallic paint called "Crystal green". Like the backpack, it's understated, even with the bony protrusions, but still stands out as a lizard's hide that could survive sunbathing next to a lava flow.
