I finished this little guy a few weeks ago. I am really enjoying Age of Sigmar as a spark to just paint lots of 'odds and sods'.
He's one of the older single-piece minis from the 7th edition of Warhammer. I love these guys as they have so much character, despite being one-piece sculpts. I wanted to see how my grey technique might work on cloth, and for that reason needed to alter the traditional skin tone. With a more traditional skin colour I feared his flesh would have just sunk back and there would be less contrast in the miniature. I'm not sure the icon on his shield works though. I did think about painting it yellow, but feared it would distract from his face, but I'm not sure grey was the way to go.
I'm thinking about doing some terrain for this grisaille series, but we'll see if that comes to pass. I also want to test if I can get bronze or brass into the mix, despite retaining the NMM grey for other metals.
