More on wallpaper resolutions

For my recent Escaflowne wallpaper, I decided to try a different approach to the issue of cropping for various monitor resolutions. Usually I design an image as widescreen, and then crop off the sides to fit 4x3 and 5x4 monitors. This is not a very good solution, as this often means nice details are in danger of getting cropped. This time around I tried to overlay the 3 different resolutions, so the widescreen gets a little cropped off the top and bottom, and the 5x4 gets a little cropped off the sides, but this way less is cropped total.
What do I mean?

[Note: this was an in-progress version of the wallpaper in Illustrator, back when I thought I'd make it predominantly blue.]
I think I shall use this method from now on.

What's in a resolution?

Wallpaper resolution is a tricky thing. There are so many different sizes of monitors out there nowadays that it's hard to design for all of them. Generally, you just crop things to the right aspect ratio, which does mean you have to be careful about element placement.
I have a dual widescreen monitor display at work, and generally speaking, this is a rare thing to find. So every so often I make one for myself.
The question was, how do I make this wall look good on dual screens and single screens?
The answer: Move elements around.
I made two wallpapers here: a dual monitor version, and a single monitor version, and then cropped them to fit the relevant aspect ratios.
Dual monitor versions:




Single monitor versions:




It makes a difference, doesn't it?
