From the Warp and I am loving it even more in person. I think the way I am doing it is a bit darker than the models on From the Warp though I still really like it. I started this morning with models that I had primed and put a coat of wash on. In the example what I would call "art paint" was used as a base coat, and the bottle I got just didn't work. The coverage was awful, and I substituted Codex Grey and it worked just fine, due to mine being a bit darker then the models in the example. Cleaning up and highlighting the models really helped make the wash pop.
Here are the models with wash and cleaned up areas with Codex Grey
