This is the rough I did in Photoshop for the Empire State Building project. It was originally going to have figures in the foreground when this was going to be an attempt at a Dave McKean style. But the style that came out of it would've made the figures too much like clip art. So I scrapped them.
And the final illustration. It was cropped to 11x17 and windows were added to the buildings in the foreground.
If you've been paying attention to my past illustration projects, you can see how this caught some people off guard.
