One Point I don't like on the 3d models is, that many objects use different textures for the same materials. For example, that wooden handles, the wood-walls of a building and the frame of a cannon should have the same texture, because your clonk cut only one kind of wood. In other packs, e.g. in Western, other textures could be used, but they should have one collective wood-texture, too.
The same should be valid on metal, but i thin metall should have the same colour od texture IN EVERY Clonk pack :P
