Coming Soon: The Waaaaagh Walka!

I haven't actually done any conversions in a while (not since the infamous flying weirdboy) so I went to my gaming store with no plans in mind and decided to just loot the shit out of something, anything.  So, coming soon, a Looted Eldar War Walker.  Still have no actual plans for what exactly I'm gonna do with it yet except it's gonna count as a Killa Kan.  Please leave suggestions in the box below.
