If completed an easy version beatmap that I would appreciate feedback on - it's listed on my Osu! profile (under beatmaps - pending).
I've just learned something about the whole system of submitting beatmaps I think might be important to anyone interested. After submitting a beatmap of your own, it is added to a list of pending beatmaps, that are reviewed by the moderators. They will decide whether your beatmap is worthy of being added to the list of ranked beatmaps or not. Currently, my beatmap is around the 1657th mark, meaning the moderators will be reviewing 1656 more before they get to mine. But it's not quite as simple as that, because of a thing called "kudosu" (Kudos). People are able to, with the help of kudosu, people are able to push their submissions further up the list, effectively displacing earlier submissions, like someone jumping a queue.
To earn kudosu, you can browse the pending beatmaps forums, download a pending beatmap, play it through and offer advice on how it can be improved.This will earn you a single kudosu point, which you can spend to boost the standing order of a currently pending beatmap.
