00:11:070 (11070|0,11070|1,11297|3,11297|2) There are various sounds like the kicks, cymbals that are louder than these clap sounds - I suggest you to reduce these doubles as single notes only
00:11:979 I get that it's an intense part that acts completely the opposite to parts like the vocal start, because it adds on parallel percussion, but I think this would work better at Normal or Hard difficulties, as this is a chart that is presented to starter players, who aren't very familiar with these kind of patterns -- I completely recommend to follow up the previous suggestion on vocal simplification, which could go like this: https://osu.ppy.sh/ss/19505151/d5ac
00:18:456 (18456|0) I'm very doubtful whether this long note is necessary or not. You're focused only on the "trumpet" sounds so, to keep consisent on this section it's recommended to remove it or simply change it to a single note (editado)
00:36:524 This is very heardable to avoid; The long note could be representin the fade-in but there are more prominent sounds to represent in here, such as the trumpet and/or this cymbal - I recommend to represent the trumpet with the plus of the cymbal instead while mantaining a reasonable amount of notes mapped in there (Simplification)
00:37:433 I think you wanted to give a priority on bass and vocal sounds by alternating them every 8 1/1's, and that's pretty fine, but the doubles tell me otherwise. Doubles here could work for intense moments like 1/1 kick+cymbal but this is a calm part, and even adding the fact that it's an Easy difficulty so, to make this more adequate for it's skill requirement I suggest to reduce the double amount by alternating 2 - 1 - 2 - 1 in 1/1 snapping.
What I refer is to remove 00:38:342 - 00:39:251 - 00:40:160 - 00:41:070 - 00:41:979 - and etc
