I'm moderately happy with the cornucen, signifer, and two officers as they've come out. I've simplified down the paint highlights, and it shows. I may add a few highlights once they are based.
They will not be based together. The front pair are destined for the hastati or principes, while the rear pair will stand around in relaxed pose with the triarii. At least, that's my plan. If I read somewhere that cornucens were always in the triarii then that will change the plan.
