Looking good so far. Below, I chucked in a picture of a Inquisitor scale model I finished a few weeks back. I airbrushed the armor gold, and painted the trim silver gave it a wash of burnt umber (I think), and then drybrushed highlights back over it with the gold on the plate and the trim with aluminum followed by silver. This were continually drybrushed until the result was an armored suit that looked bronze and silver without all the graniness. Why am I telling you this? Well, I havent tried the technique on anything smaller than the scale mentioned above, maybe you could give it a shot and see how it turns out. Oh, dont put a dull coat on it, learned that the hard way with an Artemis figure, his left shoulder and glove looked perfect until I hit it with the dullcoat, turned to lead after that. Use a semi-gloss or gloss if you get the hankerin to try.
