I like the work on the green sash and the lower portion of his tunic (the blue). When you try NMM it helps to get a greater contrast between the shadows and the highlights. I'm not fond of the robe colour and it seems close to the colour of the moustache. The shield symbol is a good start. Perhaps go and touch it up with the background colour on the shield, sharpening up the detail and evening it out a little. The eyes look a bit starey - but they point in the same direction (something I'm not guaranteed to achieve).
