I was doodling around on the ol' comp and came up with this; a highly stylized comic-bookish Jack standing against a darkening New York (if you check out the original photo that I stole, you can see where I went over it with a black airbrush to make it look like the darkness was seeping out between the buildings). Check out the bars of shadow across the Statue of Liberty; I wanted it to be kind of like the hand of evil creeping across the city.
Then I added in all the text and copyright junk. Oh, and the weird looking moon is mine too.
Techincally the background photo is copyrighted and "not for commerical use", but it's probably okay for you guys to look at it.
Here's the source photo:
Oh yeah, it's not really the right size for wallpaper, but I still think it looks pretty good.
