I've been playing this game called "Iron Harvest" which is a real-time strategy game set in an alternate history Europe where diesel-punk mechas were developed during WWI. Now, in an alternate WWII, 3 nations (Polania, Saxony, and Rusviet, based on real nations) fight for control of Europa. However, in the Operation Eagle DLC, you can play as Usonia, or the US. I like the design of the faction so much I wanted to draw my character in this style.
