So many things to compliment. The cloak, wonderful work. The design is very reminiscent of Assassin's Creed-style, whilst the 'eyes' what I presume is a tool or device for vision. The grunge effect is beautiful, I love how the train system works well with it. I feel the person under the cloak is also hiding something too. A corrupt past, not from his or her choice but with the line of work - he's dull to it now. He isn't afraid of being seen, he'll take whatever chances he needs whether you notice or not.
Brilliant, creative and deep.
The only thing noticeable that isn't working well is the bottom-left - a little 'unfinished' to me, it stands out (but I understand this may be because of time-limits, etc..).
