Here are some WIP shots of my first plague drone unit. Four drones with Standard. These will have the Plague Proboscis option. The large stingers are from spawn bits and could represent the stinger option (not that I would use that over the poison from the proboscis).
I rotated the abdomens of the left and right models slightly to break up the lines and add to the movement I am trying to depict. The center model will appear to be "pulling up and back a bit as the outermost are moving forward. The one in the back is a bit more generic. Next bit is pinning on the wings (unglued as I will keep them off for painting).
