00:57:194 (1) - this should probably end on the white tick because right now it sounds out of place. i know you're representing the guitar hold + the vocal hold after. you could either just move it to the white tick or put a circle in there to fill the gap https://ibb.co/BBVXNyV like this
00:00:890 (1) - this is faster than every other slider and that's just kind of weird. i think it's because the song's offset and the green line start on the same offset. i think you can just edit the base sv then you'd be able to change every greenline to just x1 and it won't be an issue anymore
no hitsounds at all anywhere. it's aesthetically kind of ugly (it looks good for a new mapper though!!) maybe make the sliders move a bit more circularly and line up better. clean up the bursts a bit(you can convert sliders to streams/bursts which really helps with general shape look, and feel)
besides that you have some potential!
