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.
