00:00:816 - 00:08:799 - u started with single note to express guitar sound - simplified hammer on / pull off sound // 00:01:783 - 00:01:904 , 00:03:719 - 00:03:961 with double notes. I love that way, but LN is not quite matching for this flow tho.
00:08:799 - u changed the structure, focused on another guitar with LN and drum with single note. As a result two guitars meet at 00:08:799 as a same shape, it feels they are same thing tho. I recommend u to change LN for first guitar sound to single and double as u did at this part!
00:05:654 (5654|4,6138|1,7106|6,7348|2) - single // 00:06:622 (6622|3) - double(hammer on here)
00:13:396 (13396|3,13396|6,13880|4,14122|2,14364|3,14364|0,14848|5,15090|1,15332|6,15574|1,16057|4,16299|6,16541|5) - according to easy guideline, "Objects should not be placed during a 1/1 long note's hold duration. However, using an object at the beginning or end of a long note is fine." , these notes broke the guideline.
I know its only 124 BPM but still, this is too much for easy diff, player cant handle this. I suggest you to nerf it. rearrange into something like this :

or you can just go without the LN
00:29:122 (29122|2,29364|0,29606|2,29848|0) - how about this one https://osu.ppy.sh/ss/14888688/8042 more balance imo
if you agree on my suggestion at #1566503 ,
00:47:509 (47509|6) - this note will be the only LN for vocal sound at section of 00:47:509 - till 00:55:251 - . this might ended up weird to play. I suggest you to change it into normal short note
00:49:445 (49445|1,49687|6) - according to easy guideline, "Objects should not be placed during a 1/1 long note's hold duration. However, using an object at the beginning or end of a long note is fine." , these notes broke the guideline. I suggest you to turn this 00:49:445 (49445|1) - into single note.
01:30:090 - for this part double has impact thing, only cymbal is allowed. if it has double, it'll get same weight as 01:28:154 even though it doesn't have any cymbal. Vocal can be another plan but same weight with previous part is not really good tho, u can resolve this to delete 01:30:090 (90090|0)
01:43:638 (103638|0,104122|6) - too hard for beginner players. 1/4 rhythm should not be used actually, to make 1/4 distance between LN release and single note is not good. maybe u should select main melody or drum for making structure here 01:43:638 - 01:59:122, I recommend melody for main, some single notes for cymbal sound. It will be more smoother for beginner players and gap between NM.
01:45:574 (105574|6,106057|4) - comparing this with 01:43:638 (103638|0,104001|6) - , 01:51:380 (111380|6,111743|3) - , 01:53:316 (113316|3,113678|5) - , etc.
you can see that right here 01:45:574 (105574|6,106057|4) - is inconsistent with any similar sound surround it. I suggest you to move 01:46:057 (106057|4) - to 01:45:937 - so it will be consistent with each other.
