Skytitan buildings I worked on for TW: Warhammer 3, where I did the modelling and texturing. The individual building renders were done in Unreal Engine, the Ingame screenshots from Total War are from the Ogre Valley map by Daria Adamitskaya. Other people that worked on various parts of the Ogre Maps can be seen below :)
