I would like to share my opinion on this map.Anything below is just my personal thoughts and you can just ignore this, if you feel like it's wrong.
To be honest, I wasn't able find many things, I could say something useful about, but here is what I have to say.
1.general
First of all, you made relatively difficult and tidy map for this type of song. I like it. Music is also good, especially these high sounds on the background.
I really liked AR 8 on this map. You've probably mapped this for DT, but ar8 fits for this song just fine.
I'm playing with full area, so my experience can deviate from other players' experience, but I feel like you could map this song more energetic, with larger slider velocity and bigger spacing sometimes. 1/4 sliders are especially hard in this map, thought. I think for ranked it should be classified as "Insane"difficulty and definitely not as "light insane" or something like that. This map is even more satisfying to play than watch in editor for some reason. I think, you paid much more attention to map's play-ability, than thinks like blankets etc. This patterns looks really beautiful, though 00:40:016 (1,2,3,4) - 01:16:537 (1,2,3,4) - and most other sliders looks nice.
2.Opinion about specific patterns
02:13:929 (1,2,3,4) - It could be highly personal, but I would like to emphasis this high clear sounds with maybe faster or more straight sliders or maybe even adding more rotation to these sliders.My mind is even making connection between this high sounds and this sharp arcs on background image for some reason
http://i.imgur.com/s8UQtyu.pngFrom 02:49:146 (2) - to 03:00:451 (6) - is section I like the least. It looks like a filler and it is kind of clumsy to play, especially after previous part. Moreso, It looks like you're completely ignoring guitar here. 02:51:755 (3,1) - lack of note in between here probably is one of the reasons it fells like that. Repeat here 02:54:581 (2,3,4,5,6) - 02:56:320 (1,2,3,4,5) - is also bad in my opinion, cause music is especially loud during second stream, but repeat makes it feels like nothing changes. This section is still neat and good done, though.
03:01:755 (7,8,9,10,11,1) - I like this pattern and note placing, but for some reason it's unnecessarily hard to read. You probably should add new combo here 03:01:864 (8) -
This changes in sliders' order are really fun. 01:15:668 (1,2,3,4) - 03:41:755 (1,2,3,4) - but they are relatively rare in comparison with places like this 01:21:755 (1,2,3,4) - 02:26:103 (1,2,3,4) - in this map, what makes them really unexpected. You probably should make more places like this 01:15:668 (1,2,3,4) in your map, cause for now a player has wrong feeling of "safety" most of the time.
About section from 00:41:755 (1) - to 00:54:798 (1) - there is crescendo right here. You could emphasize this by making amplitude greater and greater with each pattern. You also could try to add more rotation in flow closer to the end of section. You actually did larger spacing here,but it's still not enough in my opinion. Song is really peaceful here, though, so i'm not sure, if it's even necessary.
01:51:320 (1,2,3,4) - this pattern is really easy and when I'm comparing it to music. I don't know you could do here, though.
3.Some things I really liked.
03:29:472 (1,2,3,4,5,6) - I think, it's perfect. Rhythm, spacing, flow, everything is perfect here.
00:58:494 (4,5,1,2,1,1,1,1,2,3,1,2,3,1,2,1,2,1,2,3,4) - really good flow in my opinion. It's my most favorite section of this map. 03:17:624 (1,2,3,4,1,1,1,1,2,3,1,2) - this is good too.
02:33:059 (1,2,3,4,1,2,3,1) - It feels really satisfying to play.
In the end I would like to say, that overall kicksliders in this song are really good done and make it fun to play.
