Hello again! Welcome to the third Official osu! Fanart Contest! We’ve moved away from the monthly schedule to allow each contest a bit more room to breathe, but the idea is largely the same. Each contest will have a unique theme to keep things fresh. This one’s theme?

Announcing a brand new Monthly Beatmapping Contest - with a twist! All restrictions are gone, bar an essential few. Do anything you like, however you like, with one exception - it must be playable at the end of it all! We call it: Aspire!
