Hello everyone ;)
Here you can find step by step pictures of the Archaon's armor. As you can see, I tried to combine warm and cold colors just like in the whole composition, too. So there is a lot of blue with warm colors.
In the attachment, you can also find photos in all of the composition, from the phone and camera. I'm not happy with the result photos, but I couldn't do better. It's so difficult to make good photos of large models. I hope some of them will be useful for you ;)
Have a nice painting :)
