That's a nice paintjob I've gotta say, I myself plan to get about 20 SoS 3D-printed since, you know, how to find 'em. I found a good vendor online that sells 3D-scans (or at least very good recreations) of Old Hammer minis, and they've got Bertha Bestraufrung.
Although I think I will be paint an army for Osterlund, that should allow me to field my kitbashed KotWW and my enormous GS collection.
