Hello there
[Easy]
Nothing really bad in that map, I'll just put a suggestion
00:32:674 (1) - Make this slider a little nicer? it really looks odd and there's no real reason for it...
02:06:274 (4) - ^
One thing you could do to make the map even nicer is to work on symetry of some sliders, like 00:53:794 (4) - or these two sliders 00:46:114 (5,6) - .
It is not top priority, but it could make the map even nicer. For exemple, for sliders that you want to make the same in different positions, remember that you can copy/paste then play with
Ctrl + G / H / J to flip horizontally, vertically or reverse the slider.
02:47:074 (1) - From here, the Drum sampleset makes the notes barely audible. If you want to use some of the drum hitsounds, think about using the per-note hitsounds.

00:50:434 (4,5,6) - Curve the slider (4) ? it would be really better imo

, something like that :
00:52:594 (2,3,4) - Hmm, this could be a better pattern, imo. this is just a suggestion, but I would have done something like this :
01:44:194 (5,6,1) - Please limit the 5% volume section to the only end of the slider (5). take the next timing section to 104914

00:09:874 (2,3,4) - The first triple just sounds awkward. it is isolated, and the next ones are far away. When you put it there, it feels like there will be lots of triples in this map, etc.
01:02:434 (9) - Very very minor thing, this slider could be slightly improved, and look nicer :
01:45:154 (6) - Put a finish on this note
01:46:114 (1) - Why this whistle ? (applies to the same following whistles) you could switch them to a soft-whistle or a soft-finish (you can quickly switch to the soft hitsounds per note with the boxes on the top left :3 )
02:47:074 (1) - From here, the Drum sampleset makes the notes barely audible. If you want to use some of the drum hitsounds, think about using the per-note hitsounds.

00:23:794 (4,5,6) - I understand the fact that you want to make a cool pattern, but at least space these 3 an even way
00:33:394 (2,3,4) - I'd suggest something like that :
SPOILER[img]00:33:394%20(2,3,4)%20-[/img]
00:46:954 (x) - The normal-whistle just sounds horrible here ;~;
00:50:194 (1) - removing this new combo would be better imo
01:00:874 (1,2) - That's odd, unstack these two circles, it will be better.
01:00:994 (2,3,4,5) - This spacing has no sense at all. I'm not against jumps, but here it is just meh.
Another point, the normal-whistle here just rapes your ears...
01:04:234 (3,4) - Same stacking problem
01:06:994 (1,2,3,4) - The specing here, again. at least make something consistent, the patern itself doesn't look good, imo
01:08:674 (7) - The slider here feels like it starts on nothing, and the fact that the voice actually starts 1/2 later makes this feeling stronger. You should either make the slider start 1/2 later, or change the pattern so there's a note on 01:08:914.
01:30:994 (4,5,6,7) - Stacking these notes like that makes it huh, not cool
01:35:554 (5,6) - That jump alone feels a little random...
01:51:634 (2,3) - Huuuuuh that's huh, not cool. You should really change it.
02:48:034 (4) - Nooo that zigzag is poorly done, you should improve it

I'm not particularly fan of the later diff, there are lots of jumps that feel really random, or too much isolated, and sliders/patterns that doesn't look cool, or could really be improved. I showed some of them, try to think about having a look on your map considering the same things I showed up.
Good luck for rank anyway :3
