I finally finshed this guy the other day. Lots of washes and layers to get a suitable grimy look but I think he came out alright in the end.
I didn't realise just how much detail there was on this guy until I really got started on painting him. I had to take a look at the pictures of Forgeworld's finished version just to see how someone else went about blocking out all the colors.
