So, this is what it looks like after an evening's work. As you can see, the basic colours are all on there, and if I don't get time to back to it this month I'm going to call it done. Like any Reaper Bones model, the mould lines are an ugly mess, and I kept finding them when I thought I'd got them, but ... eh. It'll look OK on the tabletop. I feel like it's at about 80%, and if I get the chance to touch it up a bit over half-term I can get it to about 90.
I was originally going to paint it in naturalistic colours, but I wanted it to be more consistent with the rest of the army, so I went for a white-and-black colour scheme with the side heads represented in the army's green and purple accent colours.
