That's an amazing conversion, and I really like what you've done with the coloring.
Thanks dude,but basically it's quite simple. Basecoat with codex grey, black wash, some brown wash for the edges, another black wash for the edges and then the MIG light and dark rust pigments.
Very cool. I've got a KVII kit I was planning to combine with others for some traitor tanks. I like the sponsons on the turret, good solution that lets the treads stay open. Good use of the crew to help visually bring it into 40K scale.
