Below some pictures of the various dry-brush stages:
|Base painted with Scorched Brown|
|Dry brushed with Shadow Grey|
|Dry brushed with Space Wolves Grey|
|Dry brushed with Fortress Grey|
I'm planning to add some foliage to the bridge in a later stage. I'm in a bit of a hurry, because I needed to finish the bridges for our upcomming battle report "The Bridge over the River Chai".
