Sorry for late modding.
[Easy]
00:01:464 (1) - unrankable, lack of recovery time. For a spinner in Easy diff, 4 beats recovery time is required.
00:14:545 - usually big tick need a clickable item, becasue mainly strong beats are on big tick. Using slider end here, if you skipped the strong sound, then you will risk a disqualify.
00:16:987 (1) - nc is not based on vocal sound, but the big tick, this is the method how mappers put nc. therefore 00:16:987 (1) - del nc, and add a nc at 00:17:336 (2) - .
00:18:382 (1) - same as above, but no need to put nc at 00:18:731 (2) - . In easy and normal diff, mainly is 8 beats one nc, or you can say nc every 2 big tick. In lower diff, it is better to keep the nc position constant. This modding suits for all songs.
00:22:917 (1) - 3/2 beat slider on 00:22:917 - . suddently change for 3/2 spacing is quite weird to play for new players. and 00:22:917 - is also the ending for the sound started from 00:22:743 -
00:48:033 (1) - suggested ctrl+g this pattern, it is better in flowing to slider (2)
[Hard]
I think you can increase AR a little bit, seems too many objects show too early. maybe 7.5 is better.
00:23:092 (1,2,3,1,2,3) - this pattern a little bit hard for Hard diff, just becasue it is linear flow, first 3 is to left but suddently turn to right. no need to fix it if you want, just hard to play for new hard diff player.
00:52:219 (1,2,3,4) - linear flow for 5 clicks, also hard to play. also, fix it optionally, not a problem for rank.
00:42:452 (1,2,3,1,2,3,1,2,3) - also hard to play, same as above ^
00:58:498 (1) - del nc, in hard diff nc should be added for every big tick.
01:36:871 (1,2,3,4,5,6,7,8) - also, not a problem for rank, but in hard diff usually mapper map 4 circles max in a row, I mean for the normal cases, of course you can find out some exception.
Overall, I think you can focus more on patterns, especially on Easy. Pattern seems too random, and not quite good look for me. I really don't know how to tell you how to fix it, all about experience? osu still a rhythm game, for Easy to Hard diff, rhythm is okay for me. This song is in maimai right? there I think you can use the diff name in maimai: Easy Basic Advanced Expert Master Re:Master
