He looks great - I really like the steam punk aspect.
It might be a challenge to get steel shrouding for cables that is light and flexible enough. (I know it might seem like it, but I don’t get kickbacks from CableOrganizer - they just have a lot of what I was looking for for mine). Jameco has some braided sleeving as well, but not quite the same range.
This one might be light weight enough (sold by the foot):

There area also some mylar (silver or gold) and chrome finishes on PET braids. I got the carbon fibre look ones, not sure if that would really fit with steampunk, though.
