At Derby, on impulse, I picked up a set of Zvezda HYW English Knights on the B&B. Included in the figures was a model of Edward, the "Black Prince" The heraldry was all moulded on so the figure couldn't be used for anyone else. Luckily I need a commander for my Hundred Years War English, and this is just the character.
I changed my usual style of block painting over to a black undercoat then dry-brushing progressively silver, then white, then yellow, before touching up the blue and red areas. Overall it has certainly brought out the heraldry well.
