Help finding the source for some cool artwork

I ran across a video (see 1:23) that has a really cool fanart of Spitfire, possibly dressed as Artoria from FSN (or, given the source, one of the Smurfs -- I forget the proper name -- from Warhammer), on a heap of defeated changelings. I can't find anything via Google Images. Does anyone know where this is from? It does not help me that both settings are only familiar to me by hearsay, so if the image IS from either fandom, I can't tell which it would be, or if I'm altogether wrong.

Please let me know.

I don't remember how I came across this post, but I figured I would post this in case you're still interested. I found the image source in just 2 minutes by searching for the artist name you see in the top-left corner. https://www.deviantart.com/seanica/art/The-Captain-475825700

Ah, sorry that I missed your post. That is the one I was thinking of, and quite helpful. I must have somehow not seen the name. (Usually I'm more observant than that...)
