@Iyandagar: Thanks. I have never used washes yet in any of my paintings yet. I will have to give them a try. Thanks for the comment and the suggestion.
Looks pretty sound to me. All I would suggest is to try washes to add a bit of depth and differentiation of the colours and armour/cloak. Obviously I would experiment on a cheaper plastic model until you find a style that feels comfy. Good looking model though, nice one.
