To be honest only the slaves of Nagash have any form of Undead monster... the naff-looking old gorilla Bone Giant, another relic from the 6th Edition era where they had less of an idea on what to do with Tomb Kings to separate them from Vampire Counts, also doesn't fit in an army truly loyal to Nehekhara. What is frail, ugly bone for a monster, when compared to glorious stonework carved under the orders of your King?
I still love my Carmen Miranda bone giant. That being said if we went full Tomb Kings fluff I agree with you.
A 3D-printed sculpt that can be found on Etsy. Probably the most affordable and fitting proxy around for a Khemric Titan.
Decent, but the horned skull doesn't fit at all... that's more something you'd see on a Chaos shrine, or a much more generically 'Warhammer' terrain piece. For Tomb Kings it should at least ditch the horns on the skull, or better yet replace it with a Pharaoh or animal god death mask. Also the two smaller figures on the taller plinths either side of the steps aren't detailed enough to see what they're meant to be. The thing is with AI right now is that it still follows innately computerised logic, largely shaped through the parameters you give it (which also makes it particularly dependent upon you supplying the right sort of parameters it can follow; if you don't give it enough or you're not specific enough, the output ends up an unholy mess as said logic becomes confused - especially where humanoid hands are concerned ). Thus is it still very much just a glorified and especially complex computer program, rather than actual intelligence that is artificial. I agree it can be helpful as a tool (certainly in some of my creative ventures with it, it has proven itself helpful in overcoming writer's block), but in terms of capacity for imagination and creativity, you can't beat a particularly sound and bright human mind.
