Thanks man, I just started guard again and I wanted to try something other that Cadians lol.The metallic edge highlights look great, nice job.
Are you going for a Gem effect with the lights? If so, I usually base coat, dark wash, and then highlight the bottom right of the Gem with two blended layers of progressively lighter base coat. Finishing off with a white dot on the top left. Either that, or just quick basecoat, wash, then highlight with a watered down basecoat and gloss varnish for a quick effect.
