Here's my latest and greatest Maria-Sama ga Miteru wallpaper ;) They are completely vector (except for the blur in the blue sky I had to do in Photoshop), done in Illustrator CS1, based on a promotional image for one of the Marimite OVAs (the 3rd one). The sky was originally for an ARIA wallpaper I was working on but decided was fail and the fun patterns/brushes in the orange one are from Bitbox.com. This took me about 5 hours - 2 for Sachiko & the panda, two for the backgrounds, and another for resizing them all (so much easier in PS but to preserve the colors I have to resize them manually in Illustrator).
(you can so tell I am making these on a Mac due to my designing to the left. Sorry Windows fans...)
