Humanoid
robots almost always seem to evoke dark associations and
that was certainly the case here. I selected the gold
and blue wires separately and put them on their own layers,
adjusted the blending modes to make them stand out and
then added an outer glow layer style. The background was
made with render>clouds>difference clouds applied
repeatedly, then colored with a gradient map. A rust filter
applied to the rest of the robot and a red glow to the
eyes finished it off.
