These three-part difficulty names are quite bulky, maybe you should remove one of the parts.
On every diff: 2 seconds lead-in is too long imo. 1 is enough.
Also, what are taiko.png and taikobg.png there for? They do not seem to be used by anything.

Nice map! But tick rate 0,5? :o At least raise it to 1. It even sounds better.

00:04:771 (2,3,4) - Make them symmetric to the y-axis.
00:07:128 (1,2,3) - The music doesn't really justify a triple here. I'd remove that (2).
00:10:128 (1) - Again, symmetry.
00:41:628 (1,1) - This looks kinda weird, as the slider appears almost at the same time as the spinner. Maybe remove it, put the whistle on the spinner and make that 1 beat longer?
01:16:771 (1,2,3,4) - Symmetry.
01:23:628 (1,2,3,4) - ^
01:26:843 (1,2,3,4) - I don't think this is a very good idea. I'd remove that combo altogether, as it comes quite unexpected, but if you want to keep it: Move it 1 beat earlier in time. It becomes more readable (can be observed while still spinning), less confusing (every note of the melody ist mapped instead of the 1st one skipped) and closer to the music (the current (4) sounds like it's just an echo) that way. Oh, and 1 grid up to match the axis.

00:33:271 (10) - Stack this with (11). It's the only note behind a slider end that doesn't come 1/2 beat after the slider.
00:31:771 (6) - New combo.
01:16:771 (1,2,3,4) - Stack them, to make it different from the Hard diff?
01:20:200 (1,2,3,4) - ^
01:23:628 - Why no notes?
[Ryuji-Easy]
00:41:628 (1,2) - 1 and 2 grids right respectively to match the axis.
00:51:486 (2) - 3 grids down, 2 right, so it doesnt overlap with (1). Then adjust (3,4) to restore spacing.
00:54:914 (2) - A bit too far from (1).
01:26:843 (1,2) - Remove them. Not fitting for the Easy diff imo.
Star!
