This update shows the progress on the mechanical arms of the character. As I expected it is the hardest part of the character to work on because robotic arms need to be able to move as realistic as human arms and at the same time look like hard surface mechanisms. These mechanisms design allows  360 degrees rotation in all of the joints of the arms except fingers. Arms will be attached to the mechanical slots in the shoulder area I am also planing to model a connection between them that looks like a mechanical collarbone. These element should add more sense in to these character cyborg nature.

On the image above you can see the wire-frame of the robotic arms where different colors show separate sub tools/parts of the arms. I have started with rough high poly parts first and than used re-topology to make a low poly version of them. These hands tris count is still too high and I will have to reduce the topology density of some parts like fingers and forearm. I am planning to make high poly version of these arms by subdividing it and than add some final touches to it like screws and surface details. After that I can make a final low ploy version of the arms.
Right now I am behind my ambitious schedule because I've made it in the way where I have to work on this project every day and the production steps are too tight in time that makes it unrealistic to follow because I also have to work on the other modules and they take more time that I've expected. I will try to do as much as possible from the things that I've planed but in any case the character will be presented to the highest standard as a real time rendered turntable video  .
