Funny thing being a tad older than you guys. My main drawing days were pre-SW so at that time I was absolutely fascinated (and not even remotely understanding the horror of) with WWII. All I drew were pictures of the British fighting the Nazis. Planes, ships, tanks, infantry, submarines, scuba divers, you name it, I drew it.
Sad commentary: were a kid to draw now what I drew then, I suspect they would be in for some serious long term counseling. Fascination with war, particularly Nazi military machines (spent my youth building Tamiya model kits, predominantly German), weaponry. Yup, sign him up for remedial politically correct behaviour classes. And be careful he doesn't go postal.
I suspect SW gets a pass because it is fantasy. Glad that it is and does. Nice piece up there, very reminiscent of the old drawings I did.
