I finished the Emperor's Children Champion tonight and he turned out ok. I have not really changed anyof my techniques since I did the last EC Champion. I do more of the hard edge highlighting on the sword after the green wash now and that makes it look a little more glowy and sharp rather than a big block of green metal.
The pink is done the same way. Mechrite Red > 1:2 Mechrite to Bleached Bone. Then I wash Baal Red. After that I just touch up with the 1:2 mix. If I mess something up I can always wash it again.
