1
The reason I voted for 1 is because it was the only one that had the quality, all the others were jpg and pixelated.
I didn't really "like" any of them though.
Um, what does it matter if they are .jpg or not?
jpg = fail to society
The quality and file size.
Hulk Smash!
I don't think three should be included. If you didn't know that the theme was city, you wouldn't be able to tell that the stock in the background is part of a city. I think it focuses on Hulk more then the city.
Also, it has the maker's name in the image url. Maybe... I can't tell if he made that or the maker put someone else's name in it.
