I assembled the missing Seargent from the Close Combat Terminators I painted some time ago. I think the looks really badass. I used a tabbard from the Grey Knights Terminator sprue and filled the gaps with Green Stuff. It adds a lot of bulk and presence to the model, and suits my army well as my Ultramarines characters often sport a tabbard or clothing. On a side note, the green blob on the Stormvermin Fangleader will be cut to a little piece of warpstone once it's dry.
