Some of the best game artwork I’ve seen hails not from the development studios behind games, but rather the fans. Actually, that's true of almost anything–fan work is great!
Here, we see this in action with freelancer and deviantart user, ChaoyuanXu. He’s a Chinese artist who drew up these amazing fan renditions of Assassin’s Creed. Had you not told me otherwise, I would have thought someone at Ubisoft made them. The AC3 logo being on all the pieces doesn’t help that. But in any case, these are amazing and I hope that people hire ChaoyuanXu for his talents. Freelancer life is a tough one sometimes, let me tell you! And should you like what you see here, make sure to drop by his deviantart page, which has a few other worthwhile, high quality artworks–like something from Devil May Cry.
