Nuln Oil will darken your overall tone, sure, but I'd hate to know expensive washing a whole DF castle would be - you'd want something more like a wood stain or custom acrylic medium and ink mix for large quantities and a cheaper alternative. And I'd use some brown as well instead of just plain blac...

Just wanted to post a reference pic for anyone looking to copy the KS5 paint scheme. I've added a comparison of my paint scheme, which is based on Pokorny Base Gray and a variety of drybrush layers and earth tones airbrushed onto the bricks (two overbrushed gray highlights, five airbrushed brick col...

Here's a look at the three different cavern paint jobs I've got (just now remembered I have lava too, but those aren't in competition for any new pieces). The more I look at it, the more I'm leaning towards 2.0's paint job and overall tones. Caverns 1.0 http://i.imgur.com/4Z0cLSQl.jpg Caverns 2.0 ht...
