We've all seen some good shounen and shoujo anime and manga right? My personal favorites are Fullmetal Alchemist and Sailor Moon. I want you to create a wallpaper with two or more anime or mangas associated with each to create a mixed wallpaper of shoujo and shounen. For those who don't know what those are, Shounen is anime geared more towards teenage guys and Shoujo is anime geared more towards teenage girls.

Some examples of shounen would be Fullmetal Alchemist, InuYasha, Naruto
Some examples of shoujo would be Tokyo Mew Mew, Cardcaptor Sakura, Sailor Moon

stuff like that. You have one month. Good luck!
