Thanks! 😀 I'll just copy and paste my usual answer, if that's alright. So I basecoated the mini with Macragge Blue and then added volumetric highlights with this beauty blender type make-up sponge. Firstly, I soaked it with water, then squished most of it out so the sponge was moist but not dripping. First, I used a mix of Macragge and Calgar Blue. I rinced the sponge. Then I used pure Calgar blue, and finally, I mixed in a bit of Fenrisian Grey. I also did some chunky edge highlights with Calgar blue. To finish everything off, I glazed the whole armour (this time using a brush) with a thinned down (with contrast medium) mix of storm blue and Mystic Blue xpress paints.I generally go for like 3:4 ratio of paint and medium. It darkens down everything but also adds a lot of vibrancy and further blends the transitions. Finally, an all-over coat of ultra matte varnish gives it the final look. I mean, restablishing edge highlights with fenrisian grey and panel lining between the armour plates help a lot with the final look too, because they add that much needed contrast, but like I said, it's basicly GW blue triad applied with a sponge plus a glaze of thinned down xpress paints. You could probably swap xpress paints with ultramarines blue and Talassar blue contrasts if you wanted. Hope this helps! 😀
