This scheme looks great. I especially love the purple as an accent color.
I am just starting an Empire army and have everything built. I will be using a blue/yellow scheme, but after seeing your I wonder if I should add an accent color.
Would you mind outlining you procedure. I am trying to figure mine out at the moment. Did you prime white or black? Did you have to line the figure to get that great definition? Are you drybrushing, washing, layering?
Again a great looking scheme.
