Ok, i decided to do another images analysis and i think there are some really different versions of the same game between the “norman campaign” and the"fan preview gameplay". This last one version it seems really recorded months ago and all models are not really defined.
Fan preview gameplay
and some images taken from official screenshots
you can see how textures are not defined (arms, faces, feet etc)
From the Norman campaing
William the Conqueror?
So, the basic models are not bad at all and as i previously said little improvements on textures and colours (for example the weapon blades should be seem iron made not plastic) and more polishing could make this game more attractive for many people.
