For me, that’s one of the best Rogue One fan-made pieces I’ve seen yet. I don’t mean fan-made as a knock, by the way. I just don’t know how else to quantify the artwork of someone who doesn’t work for Disney directly or who’s work isn’t an official one-sheet. There are some craaazy talented artists out there.
I’m partial to Dan Mumford’s style. I’ll try to find his Rogue One piece.
