Landraider almost there

I am pretty happy with how the Land Raider is turning out.  Overall the greenstuff makes a nice Plague-like ooze and some of the bones I put in actually look pretty cool.  The only thing I would like to figure out is how to properly do MUD or dirt off the tracks.   I made the tracks kind of a rusty metal which actually looks cool but I like the idea of having a little bit more on that front.

Almost wrapped up with the CSMs which is only going to make me start eyeing new armies, or possible  a new mini system. Gonna need my fix somewhere and I cant go back to WoW.
