I've been on a bit of a binge making artwork of the Others while I'm rereading the series. These were my attempts at a lore-friendly depictions, since I feel the show pictured them too ghoulish and old. I also based the following on a study of cold, ice, crystal patterns, and a kind of alien, mythical beauty. Please let me know what you think, and how you've always pictured the White Walkers.
