00:11:157 (11157|0,11494|3) - bit empty here, more look like as Easy than Normal. Might add something to recovered the gap between Hard, it's 1/2 regular notes beside the sliders.
00:16:192 - Suggesting this pattern for comfortability https://i.imgur.com/Y9zk4Lu.png. The main reason is to make the snare which is supposed to be double like you did before at 00:16:192 - . If accepted, you can also 00:16:529 - add note beside the LN but I prefer single LN for drum rolls
00:25:293 - add note to 3 for double snare like you did at 00:26:473 (26473|2,26473|3) - which is a strong cymbal sound with snare.
00:26:136 (26136|0) - Add a note in 2 then remove 00:26:304 (26304|1). This might fit for a normal diff.
00:26:810 (26810|0) - move to column 2, much better to be pressed on index finger and fits along with 00:27:316 (27316|1) -
00:35:743 (35743|1) - move to 1, much better since same sound as 00:35:406 (35406|0) - for technicality
00:36:080 (36080|2) - move to column 2, much better to be pressed by both hands just like you did after this note at 00:36:417 (36417|2,36417|0) -
00:37:765 - should be double as well because of the strong sound similar to 00:37:259 (37259|0,37259|1) -
00:38:102 - Suggestion - https://i.imgur.com/jP3N4J3.png very comfortable pattern for normal difficulty.
00:39:282 (39282|2) - move it to 2. this section has more notes on the right part than left. Moving this note to the left might make it balanced.
00:44:170 (44170|1,44844|3) - is not advisable for normal. Would recommend to reduce 00:44:170 (44170|1) - until 00:44:844 -
01:02:203 - Suggestion: https://i.imgur.com/MWOMb7g.png the two LNs represent drum rolls for normal range.
01:07:765 (67765|0) - reduce to 01:08:102 - and add LN at 01:08:102 - until 01:08:439 - for emphasizing drum rolls again.
01:12:653 (72653|2) & 01:12:821 (72821|1) - move to 4. based on the sound, moving these two would match.
