I modelled the helmets for the Senate Commandos this morning. They appear in The Clone Wars episode, "Cloak of Darkness".
There are two types that we saw in that episode, the open face Captain Argyus helmet and the Closed/visor helmet.
I don't have enough time now but I plan to build one of these soon using the card/fibreglass method. These models will be unfolded the same way I usually do to make 2D templates to build them from.
Hope you like 'em!!
