Welcome to the forum and back to modeling.
I just got back into it recently as well.
Shepherd Paine has a really go book on dioramas that covers just about everything.
While I'm not familar with your build subject but after a quick google search there are a few picture references out there.
I would suggest asking for information in the Armor section of the forum, those guy's really know their stuff.
Looking forward to seeing your progress on this poject.
Cheers
Eric...
