Old male armour

[Jakko]

I'm not sure it's really working yet. If I were you, I would add some bits of chunkier mud to the tank as well, and go over the mud effect witha different colour as well to break up the monotony.

Also, keep in mind that mud and dirt would fall from the top run of the tracks as well, so not only the lower sides of the tank got dirty, the upper sides as well. Mud would also get thrown onto the roof by the tracks.
