The Brotherhood of Luna received some reinforcements in the form of a Terminator squad. I went for all halberds except for a single daemon hammer, with a psycannon for a heavy weapon. This seemed like a decent load out for a flexible squad.
These guys were my first experiment with airbrush shading. I basecoated them with Mechanicum Standard Grey and then did a xenithal highlight with Celestra Grey. I then painted the Celestra Grey onto the armor plates to get the same finish as the previous squad. I think the xenithal highlight helped this step go faster, but it resulted in weak shading in the recesses of the upward facing parts of the model.
In the future, I think I'll skip that step and just basecoat the model with the middle layer color (in this case, Celestra Grey). I can then go through and shade the recesses and add the highlights manually, thus getting strong contrasts without the time consuming process of getting a flat coat of such a light color.
