The right term for the vambraces is "bracelets of submission". But since this jewelry became more and more a part of an armor in the development of Wonder Woman, I use the term vambraces. Textures and normalmaps are made manually. Delete groups are used. To get the same metallic effect, connect the color input of the glossy shader to the output of the texture, reduce roughness to 0.1, delete fresnel and use a fixed value of e.g. 0.7 for the diffuse/glossy mix node. The transparent node is not used. You can also duplicate the material and use a more diffuse mix for the leather stripes. The demo picture is created this way.
