Thanks, all!
There's been some reshuffling in the orcish ranks. I kitbashed/converted a hulking orc hero and found a new leader in the form of a partially painted black orc, who has now been given a bow. I'm hoping to finish them both off tomorrow or Friday, in time for the weekend.
For now, the crossbowman is relegated to the ranks or even the sidelines; the orc in the horned helmet is the new leader. The big guy, if painted in time, will be a 'big un' - possibly paired with the small Marauder orc with the sword and mace, who looks like he might punch above his weight. I like the idea of an 'odd couple' set of heroes.
