Thanks for all of the encouraging feedback everyone! The War Boy/GorkaMorka mash up really is one of those tasty combos.
As is my wont, I have immediately stopped working on anything else other than pale orks since I painted that guy. I dont know if I will get as far as vehicles, but I really want to, primarily because of this (not my paint job):
Its a model scratch built/sculpted by my buddy
Captain Crooks as documented on his blog. Curtis at Ramshackle Games has cast the master and put them
up for sale, so I picked myself up a copy.
The urge to add that particular model to this subgroup of orks is extra high at the moment.
But some ground pounders first... and maybe the driver of said vehicle...
