[general]
If you feel like making this map sound awesome, I would suggest barcode mapping, or do it the lazy way and use soft hitsounds, then copy normal-hitnormal for a custom hitclap. The snare drum (the default hitnormal sound is a high hat+snare drum hit, soft hitnormal is just a high hat) does not occur on every beat, but the high hat pretty much does.
Also, you have 12 hitsounds in your entire map. If you don't want to do them, would you let me try? I can do easynormal, see how you like it, then if you do, I'll do the rest.

01:23:614 - Amazingly I thought 30% was too loud for this. The drums are heavily muted which give it a different sound than just decreasing the volume. A custom sound would be better here, but I think 20% works as well.
However, that's all at full volume. If you play at 20-30% osu volume, wav files are much softer when compared to the music, so there's not much reason to do this as the player can customize how loud everything is.

00:34:202 (1) - Is making this a stream too hard for HD? Because I keep moving off the slider before it's finished
01:22:202 (1) - and here.
00:11:614 (1) - after I missed the next two and went back to check on it, I noticed I skipped over this one, but it wasn't as hard for some reason. I think it's because 2-4 are stacked together and only 1.13x distance, so it's easier to read.
01:20:967 (2) - 1/4 earlier
01:21:143 (3) - shorten so middle is on 1/4 snap.
01:21:849 - consider adding note here if you do ^.

00:25:202 (6) - It's a good idea to keep all circles/sliders inside the grid, not hanging halfway off. I never put any note above y=16 or below y=368 on circle size 4, since using a different skin, or using easy/hard mod can cause notes to be off the screen or under the HP bar. Just because the default HP bar has transparency where you put (6) doesn't mean mine does.
01:32:702 - nothing in music here
01:33:320 - this is actually the piano here, nothing in the drums. If you want to map drums, delete it.
