Reverse Google image search returned a slightly higher resolution version of this screenshot, from which I was able to reverse image search the fanart. I found higher quality versions of the art, but I couldn’t find the source until I ventured into a Russian forum where someone posted the artist’s name. I always enjoy keeping my skills sharp
My friend said thanks 🙇
