Red: You must fix this.
Blue: You'd better do sth with this imo.
Green: Just suggestions.
[General]
could feel a gap between [Normal] & [Hard], try to make the Normal harder? (Hard has many jumps, but Normal has a slow slider speed even slower than Easy, also a short spacing...)
maybe offset +3~+5, not really sure.
[quo's Easy]
i think you could increase the Stack Leniency a bit... 0.3 is a little weird in Easy and may cause confusing to newbies.
00:45:894 (4) - add finish at the end?
00:55:776 (5) - miss a whistle here
01:38:129 (3,4) - i'd prefer to switch the place of the two notes (maybe also 7&8, but it's related to the next notes), since we don't need tricks for newbies ..?
01:59:306 (6) - whistle?
02:02:835 (1) - finish
[Normal]
increase the Stack Leniency... same as Easy
as i said in General... i strongly suggest you to make this diff harder to fill the gap.
00:43:070 (1) - end 1/2 earlier
00:47:659 (1) - remove new combo
00:59:835 (5) - whstle
01:20:482 (1,2,3) - all end 1/2 later, (also 01:26:129 (1,2,3) - then add reverse to 3), it fits the piano much better
[Hard]
00:47:835 (2,4,6) - remove whistle
01:02:394 (4) - it's at a very strange place... reduce one reverse, and move it 1/4 later. you can add a circle at current place instead of that reverse.
01:11:129 (2,1,2) - i'll say no to this spacing...orz. maybe sth like this

01:20:482 (1,2,3) - same slider suggestions as Normal
01:37:423 (1,2,3,4,5,6,7,8) - the jump starts a little suddenly... and yeah... hard. 1.5x spacing is enough?
01:53:217 (4) - same as 01:02:394 (4)
01:54:717 (1,2,3,4,5,6,7,8,9,10) - not fit.. imo
02:01:423 (1,2,1,2) - same as 01:11:129 (2,1,2)

finish is a bit overused, triangle placement is a bit overused... well seems you really like them = =
suggestion for the 2 kiai parts: if you want to use "clap at every 2nd/4th white line" technique, then just use it all the way, the change of clap pace won't make people feel better.
01:03:188 (1) - exception here, remove clap, since the whole structure is a xox ooxox
