General
Why only two diffs ? It would be a lot better with more.
Normal
That was pretty good. I'd suggest to use the biggest circles for the easiest diff of the mapset, unless you map an Easy.
00:26:435 (1,1) - This kind of placement is very gimmicky and confusing, because the spacing is not clear. The number of repeats of the sliders themselves is surprising. I actually thought this was a spacing error when testplaying it.
00:29:856 (1,1) - Same.
I also dislike the way you use the new combos. You should pair the sliders at least, but having a new combo on every note might be confusing. Your call.
For the next patterns, your combo placement is very inconsistent too. You made a combo for four notes for the first pattern, but then the number of notes changes per combo. Remove all the new combos, and add a new combo only every four notes (should you remove a repeat to a slider to replace it with a circle). This should make the map look (and play) better. (to help, all the notes that have a whistle should be new combos, and only these) until 00:53:518 -
00:53:803 (1) - Add a finish ? It will emphasize the change in hitsounds and will match that noise in the music.
01:28:014 (7) - New combo to match the previous pattern comboing.
02:26:742 (1) - Remove this new combo and place it on the next note.
02:50:120 (1,2,3,1,2,3,4,1,2,3,4,1,2,3) - I like this a lot <3
03:03:804 (1,2,3,4,5,6,7,8,1,2) - I understand why you did this but it might be too hard for the easiest diff of the mapset - new players have a hard time with long streaks of notes. Remove (4) and add a finish on 03:06:085 (1) - ?
03:15:208 (1,2,3,4,5,6,7,8,1) - Same issue.
03:22:620 (3) - This is lazy. :/ Replace it with a spinner (just keep the first beat) ?
03:27:181 (3,1,2) - If you replace the previous one with a spinner, do the same for these.
03:31:743 (3) - Same.
Hard
Why doesn't this end at the same time as Normal ? You should add a spinner at the end that ends at 03:44:857 - like in Normal.
It wasn't as good as Normal for me but had decent and interesting stuff.
00:33:277 (1,2,3,4) - (4) should be closer to (3).
01:01:501 (5,6,7) - This stack should be closer to (4).
01:21:172 (1) - Why is this a new combo ?
02:40:712 - Starting from here, the jumps don't seem like a good idea for me. You use it in a combo, then don't use, and it makes it a bit confusing and weird to play.
02:46:699 (4,5,6,7) - This spacing is very tricky: (3) and (4) are spaced the same way as (6) and (7), but the time gap is not the same. I could read it fine, but I think it would be better to fix it. If you remove the jumps, just space them normally.
02:48:979 (1,2,3,4,5,6,7,8,1,2,3) - Give this a better shape ? Streams that self overlap like that play rather bad imo, and are often hard to read.
Well, that was a pleasure to play and mod. I would have starred were it not for the presence of only two diffs.
