I agree, painting metal figures is no more challenging than resin.
I, too, did Andrea's Last Stand (Last Rout would be more accurate!) Makes a very good display and has several historic accuracies, Custer's firemans style shirt, no jacket and buckskin pants as well as Webley pistols. They made the same mistake just about every other Custer depiction makes, however. Before this campaign, Custer cut his hair realtively short. "Into the West" got his right, maybe the only dramatic representation to do so. It possible, accordiong to "Custer Falls" a 1930 era book based on interviews with the Lakota participants that Custer was among the first to die,. They claim a soldier fitting his description received a very serious wound before the start of the main battle.
Little Big Horn does sound like an oxymoron until you consider it was a tibutary of the Big Horn River.
BTW, very nice job on the figures. Quite evocative.
