The sadly often maligned ( by some ) Dave Summers has done all of the sculpts. Other than the Grand Crusader by Rommel Tweed, Dave has done all of the Mech, vehicle, Proto, BA and infantry sculpts for several years. He is an excellent sculptor. Given good feedback, clarifications and differing perspective images from the artists/art director, Dave really nails them! The front of the cockpit is to be shaved a bit for a gentler slope. The larger than shown in the art gap between the upper and lower torsoes was noted but would have taken extensive rework to make such a minor change.
