It is not always the amount of details that makes a good wallpaper. Sometimes, a simple yet unique idea (in this case to find a certain screenshot from an anime) can create a lovely wallpaper for Valentine's day. popiahime's "Pikachu's Valentine" is funny to look at (I totally love the bottle's design!), and it composes a sweet design for people's desktops. Even though I'm not a big fan of white backgrounds, this one fits really well to the composition and the rest of the colours.
I'm also valiantzero on Minitokyo. I enjoy many great anime/video game art (Final Fantasy VII, Rurouni Kenshin, Neon Genesis Evangelion, Full Metal Alechmist, etc), but I'm an absolute avid fan of Tekkaman Blade.
