It might just be me, but the fins on the tail of the Khador flying machine made me first think you were trying to make a submarine, and now I can't unsee it.
Maybe remove the curved parts at the end of each fin? I think they're the cause, making me think it's a guard around a propeller or something.
I like the Hogzilla.
The whole idea is based on the Kirov Airship from the Red Alert series; I really want to keep that tail fin style if at all possible. I can totally see the submarine thing; the shape has been screaming "salmon" to me the entire time I was making it.
I think this is what I'm going to go with; plop my OW1 figure on the scrapjackblimp and run a OW2+winterguard gunblimps list? Hard to tell at this distance but those weird clouds on scrapblimp are crows; not sure whether I'll keep them.
Also, my recent star wars legion terrain/painting/printing work kicks the pants off anything I've ever done for warmachine. Here's a link to my thingiverse page if anyone's interested: www.thingiverse.com/McAnultyMiniatures/designs
