This LEGO Hulkbuster mini build of the Iron Man Mark 38 Igor Heavy Lifting Suit is amazing and Legohaulic does commission these, by contacting him on the link above.
The Hulkbuster is scaled to minifigure size and it is fully poseable. It is amazing how detailed a build and accurate it is for such a small size, and the blue and grey pieces work really well together. The arms move 360 degrees at the shoulder and elbow, and the legs move too at the knee joint. Finally the head is on a hook so can turn around.
It would look better with some painted eyes, but that is just a minor point on what is a fantastic mini build!
