Change background to Ragyo since it's her theme maybe?
Besides this background is already used in another map. Just a suggestion.
InsaneIn the beginning (before 00:25:538 (1) slider speed change) it felt like the map was a lot faster than the song itself, tried adjusting sliderspeed to around 0.8 - 0.85 from the beginning and felt more accurate - take a look at it atleast, could just be me. Remember to adjust slider length if you change slider speed.
Overall a nice start, patterns are good. I would ctrl+G the first 2 sliders to match the speed of the double notes.
00:12:788 (3) - the speed you need to move between the 2 notes before it is much greater than to get to the slider itself. More even with ctrl+G.
00:14:288 (3) - same^
Now to the biggest issue I have overall. The map is quite boring. It's mainly the long single tap chains - the first one being 00:27:788 (4) - mix them up a little, make a pattern, a straight line is very boring not very hard to do either.
You already fun patterns in place like this 00:30:788 (5) - so I don't see why you lazed off with the straight lines so much
00:42:413 (1) - 00:43:163 (2) - 00:43:725 (3) - 00:45:038 (5) - Off screen
00:46:538 (1) - same^
00:48:038 (3) - ^
00:53:288 (6) - 00:54:038 (7) - Add note inbetween, pause doesn't help anyone here
00:54:413 (1) - This section of notes is awfully boring, in the VERY least, remake them into sliders lasting for 1 whole note, as you only have notes starting on every second note as of now.
00:58:913 (7) - I get that this is a slow part, but it's so long and there's no real challenge - I suggest you make some slow jumps gradually getting longer, something like
01:12:788 (2) - Off screen
01:20:663 (1) - Off screen, and also very close to the last notes even though there's a little break, you can afford moving it further away to singify the pause, and also possibly ctrl+G to be opposite of the slider right before it - just adding a bit of difficulty.
01:23:288 (1) - Off screen
01:25:725 (4) - ctrl+G
01:31:913 (6) - ctrl+G
01:58:163 (5) - Off screen
02:09:413 (1) - ^
02:11:288 (6) - ^
02:16:538 (1) - Starting with a lot of straight line single tapping here, pattern, if not all of them, some of them.
02:18:413 (1) - Off screen
There are several more you can ctrl+G like 02:04:163 (3) or 02:19:163 (2) to add more difficulty, but go through it and consider which direction is the best, bearing in mind where there's a pause, go further away, creating a more fun pattern etc.
02:08:663 (8) - Off screen
02:28:538 (4) - ^
02:30:038 (1) and 02:35:288 (1) sound like they could've been going on for that entire part, but you mapped it as she sings instead, feels random as the rest of the beatmap is going on, singing or no singing. Not only does it feel random (where it is and isn't mapped) but it's also very lazy. 02:40:538 (1) - is a little better.
02:49:163 (3) - Off screen (by a lot)
02:58:538 (1) - weird new combo pattern
03:10:725 (4) - awkward break before slider
03:33:225 (2) - Off screen
03:55:163 (4) - outside beatgrid, like several of the ones I've already said are off screen. Keep yourself inside it - it's there for a reason.
Not looking at the other difficulties as I am awful at both mapping and playing anything lower. Good luck with the map
The notes about upping difficulty is related to how your hard and insane are almost the same star difficulty.
