I never got around to picking up Warhound Titans back in the day even though I really wanted some being fascinated by Epic Space Marine. These days though the original miniature has lost a bit of it's lustre like alot of the old GW figs. Nice ideas, and pretty uneven execution across the board.
I've also been wanting to put together something unique. So reading a pdf of the original Adeptus Mechanicus rules, a growing apathy towards my pile of Mechwarrior clickies, and an idea for a future commercial product lead me to the first project of this thread.

Showing off the carapace and some of the bits.

My design philosophy recently has been running to the awkward. Rule of cool can suck it.

Some Space Marines and a second hand Warlord titan for comparison.
The cockpit is a little bigger than the head on the warlord. Which actually gives enough room to fit three crew. The original models can't really be accused of having a consistent scale.

Void Shield emitter maybe?
It still needs some work of course, finish cleaning it up and adding some procreate detailing. Let me know what you think.
