First, you should probably work on nicer spacing on the timeline. By adding more space on the timeline between notes, you'll be creating a time where the player will move their cursor to the next slider over a greater distance. Basically, a little more interesting mapping for the player.

00:00:705 (1) - Shorten the slider on the timeline by one third tick.
00:01:847 (2) - Shorten the slider on the timeline by one third tick.
00:02:990 (1) - Shorten the slider on the timeline by one third tick.
00:05:276 (1) - Shorten the slider on the timeline by one third tick.
00:06:419 (2) - Shorten the slider on the timeline by one third tick.
00:07:562 (1) - Shorten the slider on the timeline by one third tick.

It seems though that if you change bpm, you would need to change the entire map though, unfortunately.

Timing

Probably should either be higher or lower. For lower, I got 105bpm. Offset is probably the same. I'm not that great with bpm or offset myself, but there are people in #modhelp who can give you those numbers for you if you ask nicely enough.

You should probably use a 1/2 or 1/4 beat snap divisor for this song. It's not really following a 1/3 beat.

Although the 1/3 beat snap divisor works for the very first part and very last part of the song, it just doesn't flow for the rest of the song.

You need shorter sliders that fit with most of the tick marks. It seems as if you're trying to make an easy difficulty with giant sliders but with random streams (a very slow insane difficulty).

Your hit circle placement is rather random and inconsistent, though, mostly it's because the timing is off and you're having to place notes at positions where you're hearing the music but have very few nice places to place notes.

There are way too many spaces after the first initial part of the song. After setting to the correct bpm, you should be able to fill in more of the empty space in your map. Without many notes to hit, the beatmap becomes rather boring and random.

Especially with a hard difficulty with over 3 minutes, you should probably have around 400-500 notes.
