A decade ago I scratch-built a Warhound Titan. Back then my modelling skills were not what they are now (and they ain't that great now!) and neither was my painting (ditto).
So I decided to dig it out, and smarten it up. That is to say "I'm going to dump a can of Nurgle all over it." so that it can become the focal point of my Nurgle-themed Knight army.
I've decided to start on a manageable piece and selected one of the two weapons I built - a Titan Turbo Laser.
It originally looked like this:
And now, part-way through the renovation, it looks like this:
I'm not done yet - I feel that it needs more detail. I don't want to go too mental on it, though, as when I get to the main Titan carapace I need to be able to scale up whatever I do here. Pipes and tubes - I think that's what it needs.
