First wallpaper made with Photoshop SC3 featuring Nina, Arika and Erstin from anime serie Mai Otome.

This wallpaper took around three days to be complete and the most difficult task was removing the trash from the huge image found on the internet. The BG had two versions, the first one didn't suit (so the wallpaper was submited to Session Zero), and thanks to some advices from AP users, the second version did match, and I think it got pretty cool (Actually, I'm using this as a wallpaper on my Laptop).

The BG is composed of many layers try to make a transition of three diferent colors, each one representing each of the battlesuits, and filled whit some beautiful vector flower art (Downloaded from here. Thanks to Jason Gaylor)

Edit: The Image used on the wallpaper was found over the internet in a resolution higher than 2560x1600, so no need for Re-CG. I cannot find the actual image used in the WP, but i found two of the three parts that compose the image used (As you can see, they're huge).
Arika:

Nina:

So actually, what I found was a composition of three others images featuring each character with their respective suit separately.

Edit 2: It seems that the responsable for the Otome Vector is Soundtrack (Your vector ROCKZ) from Minitokyo. In his gallery, you can find both image shown here, and inside the Arika one, there's a link to the image I used.

Edit 3: Here I found the source
Arika:

Nina:

Erstin:


Hope you like it as much as I do.
