I tried to paint my Oldblood in albino skin tone to use as Gor-rok, so I thought I'd base my reptiles in the First City.
Indeed... I would use a normal palanquin/base for an actual game. I had one of those Weta dinosaur skulls from the Peter Jackson King Kong movie, and thought it would be a neat display base for showing off the awesome mental power of the mage priest as he levitates a many-ton skull with just a tiny fraction of his mind while getting down to the business of surveying the battlefield.
Looks awesome. Especially like the variation in color schemes to keep the army interesting. Despite the difference, they work. Good job.
