[General]
*Perhaps raname "Taiko" to "Natteke's Taiko"? :v
*All offsets look nice.
[Easy]
*There are only a handful of single red-tick notes in this difficulty, and my only suggestions are to make them sliders or such so that they're not so tricky to hit for the easiest difficulty.
01:09:503 (4,5,6) - Perhaps something like:

01:25:810 (2,3) - perhaps make this a slider?
01:29:503 (1,2) - ^
01:35:656 (2) - Maybe extend (1) to this spot?
02:07:656 (3) - ^ but with (2), obviously
There's more single-red notes after this,but I think I've given you enough suggestions to do the others if you choose to.
[Normal]
*A bit tricky in a few spots, but otherwise nice.
[Hard]
*2nd kiai doesn't end at the same spot as the other diffs.
*Otherwise, great~
[Krisom's Rolling]
*Could you find a better mp3? The quality of this one is much lower than the other difficulties'.
*Preview point and video offset should be adjusted a bit more for this difficulty.
01:59:980 (4,5) - This is unrankable. It's too hard to tell which is the circle and which is the slider.
