Here's a quasi-finished Salamanders Thunderfire cannon. Painting that one was fun.
I think that Techmarines got a wee bit too "heavy" in their latest incarnation and I would have much appreciated the classic setup of two Servitors manning the gun but it's still a fun model of course. I like the design of the cannon itself quite a bit and the fact that we all can field Thudd Guns again (I know, I know, there's the even more Thudd-Gun-like forgeworld one as well... )
Anyhow, look out for more finished Salamanders on here soon!
