Inscense burners in simpler terms. Lots of burning of inscense done around many things, blessing before battle, blessing of the new Rhinos and other machines, blessing new armour and weapons, blessing new acolytes/scouts. . . . etc.
I agree with what most of you have been saying, the model is nicely sculpted and all but just looks odd. The hands/fist/whatever don't suit the model, I don't like at all.
