Nice work Rob.  Followed these over on BKs Forum.   Love the Fireball Dio in particular. 

   

Ma.K is a considerable series of designs primarily in the 1/20 scale by a designer from Japan called Kow Yokoyama which stretch back over 25 years.   Well worth checking out as they can be all wonderfully dirty grimy and grungy (if you are into that sort of thing)  ;D
