The major problem of your map is that you rythm is realy dense, you'r placing notes where there is no sound or you are following an instrument during 5 sec then you'r changing of for a beat then you comeback on it to make a flat 1/2 jumpy rythm that doesn't make sense. You should try to listen more carefully the track and take a look at PoMuTa's mapset to make a less sleepy rythm, this is a major problem in the part before your first kiai, there is exemples of what your rythm should look like:
01:20:059v (1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4) The rythm is more like this (use 25% replay you'll notice it immediatly):
01:24:245 (1,2,3,4,1,2,3,4) Same problem
01:26:687 (2,3,1,2,3,4,1,2,3,4) Same rythm issue the rythm should be like
01:29:827 There is no issue for the following jumps because it makes sense with the speed up so i noticing you this to make you know that there is not only the music in the composition of rythms.
01:35:408 (1,2,3,4,5) You should remove the first slider and make a 4 circles patern instead. The melody is restarting from this point so this is easier to understand how it goes when it's starting by circles.

Kiai: An heavier experimented modder will tell you that your spacing is realy chaotic, for me that's ok in the artistic way, that fits the music's theme but when it makes your map hard to play that's kinda bad. Like these:
04:41:037 (1,2,1,2,3,4,5) The jump between 2 and 1 is realy random, like you have your cursor going ham to the Left but the next circle is to the right and it's not predictable because it's not even in the same combo. I mean you need to be more logical in the placing of your jumps, take your map and ask you "Why did i place something there?" everythin,g you'r placing must be justfied or your map will be as rankable as a casual Arles map.
04:45:248 (1,2,3,4) Second common issue that you can get on jumps: Spacing. Nothing there justifies a high spacing between 2 and 3. Just compare this spacing the previous jump between 1 and 2 this is like 1/3 larger without a reason.
04:46:300 (1,2,3,4,1,2,3,4) Exactly the same problem there, your first 1,2,3,4 patern hasn't form this is realy hard to play, it goes like a small jump then it becomes larger and larger to get to the last jump of the last patern (3,4) which is huge compared to your first jump. There is no reason for these jumps to be like this and i can notice you that this note has no reason to be 04:47:221 (4) there is nothing in the music that justfies this, the melody stopped 2 ticks before. You can correct this by making paterns more geometrical, so you will have a less contrasted spacing.
Well, iv'e shown the 3 huge issues of your map which are notes that shouldn't exist, spacing and randomness. Take your map from the begining and correct it with those things in your head then it will go realy well.
