I use a flame & coal pattern for my character pieces in my eldar army. The turquoise chevrons on his shoulders and knees are also trademarks of the force. They're the markings of all the vehicles.
well, technically a chevron is like an arrowhead or triangle. For example, NCO rank markings in the US Army are chevrons.
However, technically, that's a very well painted miniature, very clean and easy to look at, perfect for gaming.
