APH - Grow up to be fearless

Assume the horse he's on to be an Old Don, because I was only able to find images of the more modern Russian Don OTL (Although, I'm guessing the horse should still be smaller. Or maybe Vanya's still growing?) Original drawing with just Russia can be found here, and the title is sort of taken from this gorgeous song. Have I mentioned how digital inking is an absolute pain in the ass?

Also from the war horse series:
Finland the Hakkapeliitta
WW1 Canada
