Overall:
The names you choosed for the diffs are incosistent with the ranking criteria. I recommend you call the Easy of Light Easy, the Normal of Easy and the Hard of Normal or a random name as you can have any name in the last diff.
SPOILER
Mapset
Mapsets must have at least two difficulties of the same game mode, one of which must be an Easy/Normal level. It is possible for Marathon difficulties to have only 1 difficulty, but it must be named Marathon for the BSS to allow the submission to pending.
The mapset must have a well-designed spread of difficulties, containing at least an Easy or a Normal difficulty. This is so that players of all levels of experience are able to enjoy maps of the songs they love.
The difficulties in the mapset must be in a consecutive order. Easy or Normal can be skipped if the gap in the star rating spread allows it. The order can be seen in the chart below. If your mapset has two difficulties, one of them cannot be an Insane or Expert. The lowest difficulty must be below 2.0 stars. The difficulty level of Taiko-specific and osu!mania-specific difficulties must also follow a well-designed spread and might contain an Hard/Insane only, if there are standard difficulties present. In CtB, the spread evaluation is upon the BNs discretion. The difficulty spread is determined by the map's star rating. A map falls under a certain difficulty when having a specific star rating:
Below 1.5: Easy
Below 2.25: Normal
Below 3.75: Hard
Below 5.25: Insane
Above 5.25: Expert

Easy:
00:25:974 - 00:26:706 - circles here? This unmapped space is a bit weird as there is a rhythm on the background.
I found the hitsounds a bit inconsistent, they're too loud also. 50% should be fine.
00:49:389 - 00:50:120 - 00:50:852 - circles too? There is no need of this breaktime
Normal:
00:42:437 - circle here?^^
01:01:828 (7) - what is this slider standing for here, there isn't any sound on the song to have a slider here. Instead, I would rather a circle at 01:02:194 .
I found the hitsounds a bit weird inconsistent, they're too loud also. 50% should be fine. (2)
Hard:
00:05:852 (2,3,4,5,6) - Use snap distance of 1.4x or what you prefer instead of eye-placing the circles ^^
00:17:559 (2,3,4,5,6,1) - Same ^^
I found the hitsounds a bit weird inconsistent, they're too loud also. 50% should be fine. (3)
That's all, very calm song, There's no need of making a harder diff imo
