Hai I'm topkekkery. I am currently interested in creating my own personal osu! skin; but I don't know what I should use for programs. Any siggestions? Thanks :3 ~ topkekkery
From OsuMe's profile these are all good suggestions, maybe if you're planning on doing 3D you could go for Blender instead. Audacity is a good free option for editing audio.

Thanks people! Also, in response to Danger Melon, I'm actually not sharing an account and I just control two YouTube channels. I have changed my signature so this won't happen again.
