This is honestly quite an achievement Terry what Hot Toys was able to make. Never thought I'd see something like this in 1/6 scale other than in the movies. Bravo
Hot Toys should have probably reissued Armor Test Tony Stark from Iron Man 3 to go with this suit. After all, they put the old version next to the open armor at the promo. Such a missed opportunity to make the diorama complete.
I like your idea but not a reissue. I'd prefer a re-make top to bottom with updated sculpt, body proportions and tailoring. The craftmanship has improved since armor test tony from iron man 3 was made and this would also be a wasted opportunity.
