As a first chart, you can use this as a basis to improve. For instance, NEVER put match notes after scratch notes; you'll almost inevitably end up on the incorrect wheel color because you're spinning the wheel. I'd suggest putting a spin note either left or right after those. Also, it seems you use beat notes pretty sparingly during most of it, but go wild on it in the intro. Why's that? Finally, the gameplay here is mostly boring, because it's mainly match notes placed a bit incoherently and some taps here and there. But you can absolutely do better, no worries! Cheers.
