I read somewhere that Hux always looks super tired, because he hardly sleeps and works too much. That's the image. Tadaaaa. I'm too lazy for fancy artworks, I hope you still like it, it's more about the mood than the details.
I like to imagine Kylo Ren being the stark opposite of Hux, kinda lazy and entitled, sitting around in his room an awful lot and refusing to get up before room service brought him breakfast. Maybe I should draw the lavish Kylo Ren morning version, haha.
