Just picked up this box set. The miniatures look gorgeous even though they're still unassembled and on the sprues! The rules for all the models are in the box along with some fairly detailed assembly instructions. (Bellisarius Cawl has 5 full pages!) I was comparing a Seraphim Superior to Eleanor, one of the Geminae, and Eleanor is slightly taller with a much larger jump pack. Breastplate seems slightly wider but that's not discernable without close inspection. Swords seem to be the same in size and shape. Bolt pistol is slimmer in the magazine and magazine well. She does have wind-blown hair, something none of my other Sisters have and gives her a cool motion effect.
