better than CA's version

Thanks for this lore accurate alternate look (the base one is good too) !

Also, in the lore it's clearly stated that the constructs can be made of bronze, leather and bone of desert creatures

Never said it was wrong, the point is just to represent them in an other way, a way that was also shown back in the days. But indeed, some of them being made of stone isn't wrong, again, that's why I kept the basic variant and just added an other one.

CA depicted them as statues because that's what they are, as stated in the army book. I mean the clue's in the name - Necro (dead) Lith (stone).
