[General]
The video is too long compared to the .mp3, you need to cut it down.
00:10:809 - I can make the title text appear here if you want.
[Hard]
00:26:298 (5) - Clap?
00:29:722 (2) - I'd prefer no whistle here, since you haven't used it elsewhere in this section. It's a bit too sudden for me.
00:47:331 (1) - Remove the next note and extend this slider by 1/4? same for 00:48:635 (3) - .
00:51:733 - Clap here instead of the previous tick.
00:54:505 (5) - Add a newcombo here instead of 00:55:157 (1) - so it fits better with the lyric and symmetrical pattern.
01:12:114 (1) - Shorten this slider by 1/4 beat and add a note to where the slider end originally was. That way this pattern plays better and fits the instruments better i think.
01:23:690 - Missing whistle.
01:47:331 (1,2) - Rather than sticking to the constant DS I'd space them out at higher DS for better looking.
01:54:668 (4) - Clap?
02:02:983 (1) - This partial overlapping doesn't look great to me.
02:19:777 (4) - Somehow feels quite weird, try to shorten this by 1/4 and start it 1/4 later?
03:39:505 (1) - Extend this spinner to 03:40:809 - or mute the end point.
04:22:548 (1) - This short slider doesn't fit in such a calm part and sounds a bit overmapped tbh. Maybe replace it with just a circle?
04:32:894 (2) - Too unfriendly for players imo. Don't you think it's way too hard to get 300 from this note? I'd highly suggest removing the note and add a repeat to the previous slider.
[Normal]
00:26:461 (1,2) - These sliders are too long and feeling awkward to me.
01:12:114 (4) - Shorten this slider by 1/4 beat and add a note to where the slider end originally was, so the heavy beat can be clickable.
04:22:548 (1) - This note appears way too soon right after a spinner.
04:29:069 (2,3) - Maybe it's too hard for beginners to get the rhyrhm here, it might be too complex. How about simplifying the rhythm by rearranging the slider usage so beginners won't have trouble getting 300 here? This is the very end of the difficulty, so the current one is a bit too stressfull if it causes players to get the rhythm wrong.
