It's finally done. After a bunch of hemming and hawing over what colors go where, I finished it up over the weekend. Of course having all the weapons magnetized adds time to complete the work, but it's worth it.
As my supply of fenris grey dwindles, the less I'm inclined to paint the Tau. I do plan on at least the 3rd marksman and last 2 sniper drones I have. The Stormsurge, someday soon-ish, but the other 2 ghostkeels might end up on ebay.
