Well, I got some time to work on the Farseer and Warlock models this weekend, and got them to the point where all that is left is the basing.
The warlock: First picture shows work in progress on Saturday, and subsequent three pictures shows the completed model. The last picture was done after I decided I was unhappy with the blue highlighting on the mask brow and went with a thin line of codex grey instead.
Next up, four guardians to test out variations of the painting scheme and settle the question: pink as the last highlight, or blazing orange? The warlock and farseer make a strong case for blazing orange.
