Okay so here's the deal, I photo-shopped the image and made a static front view that prints out a model exactly 24 inches tall (On my printer using my editor's print graph I hasten to add). I'm satisfied that this is viable height for a Warlord towering almost 2.5 times the height of a Warhound.

Now that I have the overall height I'll remove the armour and draw in the structural detail.

BTW that's 24 inches to the lower margin of the image because we mustn't forget the foot pads.

I calculate the center disk of the foot to be about 3.625 inches in diameter.
