Generally, the hitsound volume is very loud, consider setting it to something like 60% from the F6 menu.
00:17:787 (3,4) - Notes overlapping each other like this are considered aesthetically unsightly, essentially they don't look very good. There are a lot of this type of structure in the map so consider going through and editing them so they don't overlap
00:29:276 (7,8) - You can make a blanket here, which means making the pattern more like
https://osu.ppy.sh/ss/7438485 (see how the approach circle is surrounded by the slider)
00:45:872 (3,4,1) - "1" has the sound in the song with more emphasis so it should be further from the note before it, not closer than "3" is to "4"
00:48:425 (1,2) - "2" is quite close to "1" despite being much later musically, moving it further would be better
00:50:021 (5,6,7) - Consider stacking these on top of "3", looks better imo
00:57:361 (6,7,1) - See how all of these are the same distance apart in the music but in gameplay 1 is randomly closer to 7? This kind of spacing inconsistency is discouraged unless there is some sort of lower emphasis on 1, which is not present here
01:18:425 (4,5) - This looks similar to patterns like 01:13:318 (3,4) - 01:05:659 (6,7) - but the time to hit the notes is different, so consider moving 5 somewhere not stacked on the end of the slider
01:47:787 (1) - Try putting a note where the spinner starts and moving the start of the spinner 1/4 later, like
http://arf.s-ul.eu/K29FrVyi02:10:127 (6,7) - These are very close together despite there being a large gap of time between 6 and 7. please move them further
02:24:648 (4,5,6) - In previous patterns you would make the sound on "6" be further away from everything, but here it is "5"? Better to be consistent and have 5 be close to the slider and 6 be farther imo
02:34:223 (3,4,5) - Same as above. (notice how just before this pattern at 02:33:106 (5,6,7,8,1) - you made only the last sound be farther?)
Nice song choice, sorry for short and bad mod but hope you continue mapping and getting better! \
