Hello there.
I don't know how much I can help, but I will try. I hope my words do not sound too harsh though.
Easy:First of all, you can try curving some sliders more, to make it look nicer, because some of your sliders are just straight, which gets boring to play after a while
and btw,
dont listen to all issues of Ai Mod when it comes to spacing of seperate beats, because I find some beats a bit far away for normal though Ai Mod insists on them to be so far away.00:17:390 (2) - closer to previous slider
00:23:705 (4,5,1) - I am not sure, whether you should make them overlap a bit, because it comes a bit sudden. It's up to you^^
00:27:495 (1) - can you make this point directly to the next beat?
00:34:126 (5,6) - you can make this a slider because I find the latter of the two hard to get
00:37:916 (2,3) - I am a bit against these, because I'm not sure, whether it's good pattern here... You can change 00:36:969 (1) to a returning slider and curve it around 00:38:547 (2)
00:45:495 (6) - The new combo starts here, remove it from 00:46:126 (1)
00:46:758 (2,1) - you can add a beat inbetween here to fill it
00:53:390 (1) - remove nc
00:56:232 (2) - wow, 1/4 slider? I find it odd and prefer it to be double its length
00:59:074 (1) - remove nc
01:06:337 (1) - same with the slider length, extend it a bit
01:12:337 (8) - add nc
01:16:126 (1) - remove nc
01:16:758 (2) - slightly to the right, so the slider points directly at it
01:18:021 (1) - extend this to be double its length and drag 01:18:653 (2) to 01:18:969 adjust the sliders position like you want
01:22:758 (1,2) - I find curved sliders pretty fitting here
01:26:547 (3) - double slider length
01:27:495 (4) - too far away from previous
01:37:916 (6) - you can make this curved and double so long
01:43:916 (1) - remove nc
01:46:758 (2) - double the length
01:54:021 (8,1) - too close. You can move 01:54:653 (1) a bit higher and to the left
01:56:863 (2) - extend length
01:57:811 (3) - nc starts here (? I dunno, you can leave it too)
That's for the rough over view^^'
Hard:Wow, spacing is really pretty, crystal! I really like its flow, good job~
01:00:969 (5) - I have no problems reaching it, but this seems a tad too far away... and we want this map to be playable not only for tablet users...
That's it for now, I think, I'll come back in a while again.
Hope I could be of help.
PS: Crystal, Why cant I view your profile, btw? I thought you were banned or changed your name or so? What happened?
