As promised, I'll work my way from bottom to top, painting one assembly group after another. Usually I feel more comfortable painting smaller models, but to break down such a large model in smaller parts really does the trick for me. By now I've finished the legs (apart from the crotch banner).

The metal structure of the legs was primed black, then airbrushed with Army Painter Gun Metal, leaving a bit of black in the recesses. Then I applied a thin coat of Army Painter Dark Tone Ink as a filter. I highlighted the metal by drybrushing with Army Painter Shining Silver. The metal trims of the armour panels were highlighted by brush with Army Painter Plate Mail Metal instead.

What do you think? Next up is the upper body...
