I'm in the process of writing up the mod posts for Normal and Easy, so here's my view on Hard, just to give you information right away.
Hard:
-First off, this is more [Insane] than [Hard] in my opinion.
-Second, I'd say for you to not map anything before your first bookmark (00:16:021).
-Third, check your spacing in some parts by going through it with Distance Snap on. Just to checkk.
-Fourth, when you have these constant 1/2 streams, try to make the patterns more varied. Like, at the part right after the spinner, you could have 8 clicked beats, and then 4 Etna sliders (each one going from one white tick to the red tick right after it in the 1/2 divisor). In fact, it'd feel right to do that, since constant clicking is too tiring.
-00:26:713 (1) - Remove the New Combo mark from this, since it's a part of the previous phrase in the music.
-00:31:168 (1) - Remove the New Combo mark from this.
-00:46:612 (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13) - It might just be my own mapping style taking a hold of me here, but I feel like if you keep the same timeline rhythm here but set it to Etna sliders, it'd feel less repetitive and, well, right to me.
-00:53:443 - New timing section:
BPM: 202.018
Offset: 53, 443
Audio: Soft
-00:53:443 (10, 11) - Make these beats have whistles.
-00:54:037 - New timing section:
BPM: 202.018
Offset: 54,037
Audio: Normal
-00:54:334 (1, 2) - Check your spacing consistency. I believe that the spacing between 4 and 5 of the same combo is more appropriate for this part, but the space between the end of 1 and 2 is too close. Check your spacing consistency by running through this with Distance Snap.
-01:00:571 (7) - Put a New Combo mark on this beat.
-01:02:947 (6) - Put a New Combo mark on this beat.
-01:04:135 (1) - Remove the New Combo mark from this beat.
-01:12:451 (6, 7, 8, 9) - Make this an Etna slider part.
-01:13:045 - Delete this spinner, then put a beat at this spot at the end of that stream of beats. Put a break in right after it afterward. If you make the previous part into an Etna slider part, put this beat at the end of the last Etna slider.
-01:18:985 (1, 2, 3, 4, 5, 6, 7, 8) - Etna.
-01:21:361 (1, 2, 3, 4, 5, 6, 7, 8) - Etna.
-01:23:737 (1, 2, 3, 4, 5, 6, 7, 8) - Etna.
-01:27:301 (1, 2, 3, 4, 5, 6) - Add Whistles to these.
-01:28:340 (7) - Add a Finish to this.
Overall thought of this difficulty: For a first beatmap, I'm being rather nitpicky. But still, nice work!
