Outlining on the 15mm vehicles

After getting the camo mostly done, I wanted to do some outlining with Devlan Mud like I saw on one of Robin's videos on his Gruntz feed on Youtube.  It went on nicely, I think, and gives a reasonably subtle hint of 3D when used only along creases and corners.  Here are some quick shots of it.

Here you can see elements of the tank, such as the headlights, that I tried to throw in for detail. The are highlighted with 2 colors, but its really hard to tell from this angle and at this scale:

So at this point, Ive finished with the camo, the tired and treads, the head and tail lights, and the outlining. Well, the Mammoth hasnt been outlined yet, but I can only take so much cramping to my neck, back and hands in one sitting :)  After I get the Mammoth highlighted, I will try some weathering pigments from Secret Weapon instead of my normal drybrushing. This is, after all, my project of experiments (new scale, new painting, new outlining, new weathering techniques...cool!)!
