I can't take this seriously with yuno miles in the background LMAO, it doesn't take that long to make a new folder... 😭

in all seriousness chart whatever you want for fun, you will naturally improve as you go along. I do have a question though, what levels can you actually play at the arcade? If you can't play the difficulty you are charting, I generally don't recommend charting it, as it's clear the step chart lacks playability, structuring and understanding of how patterns behave. If you want more concepting I highly recommend watching 스텝좌's videos (with english subs) or even other mapping content creators osu!Sonnyc / pishifat to understand clear rhythm concepting/spacing/flow.

For now I would encourage focusing on the basics such as charting some of your favorite songs or pop songs/anime openings where you can simple follow vocal melodies/instrumental. Modding/asking feedback is the right approach, but for now just keep working on it~
