Nice grab. Back in the 90's, screen captures were the most popular kind of wallpaper. Those and scans of art were all over the early internet in all their super pixely 256 color, BMP/JPG glory. So yeah, screen shots of the characters in action or in a fun pose work great. Those pan-across establishing shots work nicely, too. Don't worry: as long as the thing doesn't have subtitles on you'll be fine.
Speaking of pixels... looks like everything old is new again. At least these look better than the dithering we used to see. Man those were bad.
