Think about dian sastro, think about the letter and the art. i had found some artis wallpaper icludding dian sastro wardoyo in the art style. this wallpaper is very simpe. You need not to change the size because the size is really fix your notebook.
it may not fix your desktop, but you can try to crop the wallpaper to fix the size for your desktop computer. this picture was not taken from kapan lagi, i found it from kaskus.us so you will not find the kapanlagi.com marked at the wallpaper.
