Wow! Great action scene going on there! Love the tank coming down the hill. The darkness is fine on my screen. My only suggestion, I know you will loose some detail, but maybe a smaller version of this. I kinda would like to get a feel for the scene without having to scroll the image too much. I am in 1024 res. and have to scroll up and down so I kind of have to look at it like 3 different pictures. :)

Other than that excellent job! :)
