Unmer Armour ideas

Here are a few armour concepts i came up with. This armour is a magic Unmer artifact in the book, its called 'Mechanical nerve armour' its something that i imagine give the wearer increased strength as well as being protected by metal plates of armour. In the book it describes the armour to whir softly when moving and the small metal plates move and chatter, like its almost moving itself, or its aiding the wearer to help movement. So i wanted these armour concepts to look kind of medieval with mechanical looking parts, while trying to keep it looking functional. The only problem with this, i think that some of the armour concepts turned out looking a bit sci-fi  and more futuristic. I'm still not 100% sold on any of the concepts so i might have to bash a few ideas together and see how it looks on the character with colour. I think the ideas on the bottom row turned out better though.
