Garret looks like he's dressed up for the next "Legacy Of Kain" game not for his own series, I mean seriously... he looked like a medieval wanderer/yeoman type originally, now he looks like a reject at an Goth convention. If you had showed me the picture of him without knowing it's a thief game I would have assumed it was something to do with Vampires.
That said, I haven't heard many people being impressed by this, and really it seems like yet another reboot that misses the point of what made the games what they were to begin with.
I also find it kind of amusing that Garret gets exps, rewarding him for shooting people in the head with a crossbow flat out, where "Dishonored" which is a game about a vengeance obssesed Assasin as opposed to a thief, actively punishes you for killing people by making the world increasingly hostile and ultimately giving you a bad ending.
Sometimes I kind of wonder what game developers are thinking.
