The paint scheme has progressed somewhat, with the addition of edge highlighting, use of weathering powders to add texture, and some very effective "chipping" achieved by using a piece of sponge to apply Tin Bitz followed by Boltgun Metal, washed with Devlan Mud.
The only stumbling blocks have been the shield pieces on the front of the torso and one of the knee pads. I made the mistake of hand-painting the quartering and chevrons and the final finish is pretty terrible. I am going to look into how I can fix this, and it may delay the completion of the model.
Here are some photos I posted on Twitter over the last couple of weeks, in case you haven't seen them:
