Hello, found your map by kpop tag.
What can you do better:
1. you have 2 audiofiles in beatmaps folder. It makes .osz file bigger. one of them should be deleted
AudioFilename: audio.mp3
so __ - Good Day (320 kbps).mp3 - that you don't use anywhere. just delete or cut to another folder on your pc if you want:)
2. Time your map.
there are bpm, offset and timeline
bpm is correct. but offset = 0 tells me that you didn't even try or failed to find an offset.
choose offset at 00:00:447 - after that preass Ctrl+A and place circles on timeline on nearest ticks. You'll see how much better will become your map
after that look at the map and find where you needed not the nearest tick, but another and change the placement on the timeline.
3. Just spend more time to place circles and sliders neatly. seems like you've placed them in hurry with a random click.
4. There are much work to improve your mapping. If you want i can make full mod. But after you got all above. And if you have any question just pm me.
Good luck
