Dishonored fan art Box Cover: http://vgboxart.com/boxes/360/46564-dishonored-full.jpg
I do have a few criticisms however. It still looks good don't get me wrong but the way I picture the perfect box art for a Dishonored Collector's Edition would be as follows:
A more gray and metallic color/style. Instead of those cogs and clocks the chaotic razor blades we see in some of the Dishonored art.
Show a few more screenshots. for example when they are talking about the powers show the mark of The Outsider on Corvo's hand and next to it the text. When talking about the Chaos system show a bit of the world off. I know there isn't a lot of room on these boxes but the signature things of Dishonored should be shown. The mask as a cover, the Tallboys, the mark of you know who and so on.
The Quotes are good but misplaced I feel. The front one especially, like I said I am not sure it fits quite well within the whole theme of the game. If it was a revenge quote probably. Maybe the the back one should be about revenge, I don't know but there are definitely better choices for them.
Also I don't know how I feel about the streaks of light. I feel conflicted about whether or not they should be there. I believe there should be something symbolic though. Light of hope? No, probably not. I am going to ask a friend who is a professional artist and see what he thinks.
Again, it looks great and I like it but it's not very Dishonored-like. Other than that it's really good. The best thing about it is probably the front. Not only will that get people's attention but that is cut from the first screenshot that was revealed to the public and the art style used in that screenshot is really good. I think they should draw everything on the box in that style with a little tweak on the shading. (Here is the screenshot I mentioned: http://www.wired.com/images_blogs/gamelife/2011/07/dishonored-spreadcover.jpg)
Oh wow, that's pretty amazing. I agree with all of your criticisms, strife, but it's still really awesome, especially the front, which you mentioned. That would be near-perfect (for me) if the removed the quote, removed the picture of Corvo on the spine (it doesn't fit), and redid the back.
