The Seraphim are the ones from the starter set, although slightly converted with some inferno pistols from the multi-part kit to make them a little more interesting (and competitive). I will build that box as Zeraphim in some future months who cant use inferno pistols. Happily, the Sisters are really easy to convert because you can cut off the entire hands at the leather gauntlet/glove and not have to worry about much of a seem. Painting wise much the same as every other sister with the added faff of the clear flying stands meaning you cant mount them in painting handles, so I kept rubbing off paint with my stupid hand. Power Sword and plasma glow on the sister superior were interesting to paint. I think both turned out rather well.
