Hi! Random free mod
Easy:
I think you should add a lead-in, because it starts quite early. (and the other difficulties also have lead in)
Also check AiMod
(even if it's buggy), it said 2 timing points at the same time, and true! look -
http://puu.sh/2qWfg - so it's better to check.
00:06:447 (3,1) - this doesn't flow well in my opinion, because the the slider (3) leads into a different direction
this is an example of how you could change it without ruining the distance
(and I think 1,04 is not much but it can be adjusted):
http://osu-ppy-sh.jeuxcrack.net/ss/681881
00:06:447 (3) - add new combo? because actually this is the part where she starts singing xD (and remove new combo from next slider)
00:42:718 (1) - it feels weird to click this, I cannot really tell exactly on what did you place it (lyrics or beats), because you placed it when she has been singing already, so I would suggest you to add a hit circle here - 00:42:379
00:23:057 (3,1) - i mentioned before, I think that this doesn't flow well, because after (3) players will have to go up, but it leads down, si I would suggeset you to try something else so that it has better flow and it might make it easier to play (since it's an easy)
00:50:176 - this place very empty, and a bit confusing too, I would suggest you to add hit circle
00:52:888 - ^ same as above
00:54:752 (2) - it feels weird to click this slider (probably because it starts on a red tick), so i would suggest you to remove 00:54:244 (1) - and put (2) in it's place, and add a repeat, for example:
http://osu-ppy-sh.jeuxcrack.net/ss/681928(but of course it's just an example, but at least you can see on the timeline what I mean)
00:55:600 (1,2) - ^ i suggest the same as above, since it's weird to click them, so remove hit circle place the slider earlier and add repeat and rotate it a bit or make a blanket so that distance will be fine, example:
http://osu-ppy-sh.jeuxcrack.net/ss/681930
I think it plays better and flow is still good and it doesn't change your pattern so much in my opinion.
Overall this diff is pretty nice already, so there is not much to say about it
Verdi's Normal:
00:00:854 (2,3) - I think this is too hard for the beginning of the map, so you should change (3) and make it a repeat slider, and delete (2) (it's only the beginning, so you can easily rearrange without having to change a lot of stuff)
00:11:532 (4,5,1) - isn't this a bit hard for normal? such a short repeat slider, and then players will have to hurry to reach (2), I would suggest you to delete that repeat slider and add a hit circle instead, here 00:12:210 -
00:16:108 (2,3) - I think this is a bit hard for a Normal, and the whole difficulty is already pretty hard for a Normal, so I think you could just make this a repeat slider to make it a little bit easier
00:18:820 (2,3) - ^
00:21:532 (2,3) - ^
00:45:430 (6,1,2) - to be honest I think it's weird that the distance suddenly changes to something bigger, while obviously they were closer to each other (even if it shows that distance snap is fine), so I would put these closer to each other -
http://osu-ppy-sh.jeuxcrack.net/ss/682736 - and leave the rest like that, because further on it's not that noticeable that they are not so close to each other
00:57:634 (6) - this slider leads upwards, but players will have to go down, so you should try to make the flow better here, for example like this -
http://puu.sh/2rcOL
Well, sorry to say this, but I didn't like this difficulty so much, becase I think it's too hard for a Normal, because of those overlaps and distance change because of slider velocity, I wouldn't change slider velocity on easy and normal, maybe you could be more careful about this in the future? oh well, it's just my opinion
Andrea's Hard:
00:10:007 (5) - i think this breaks the flow, because of it's placement, so I woudl suggest you to place it similar to this -
http://puu.sh/2rddl
00:16:786 (3) - this feels unnecessary and a bit confusing here, because there is almost nothing in the music at this point, so I think you should remove this hit circle, removing it would make things better matching to lyrics and beat too
00:22:549 (1) - there are too many repeats on this slider, and it's confusing and breaks the flow, because the last repeat leads upwards, so I think you should remove all the repeaps and make another short slider, example:
http://osu-ppy-sh.jeuxcrack.net/ss/682807
or
http://osu-ppy-sh.jeuxcrack.net/ss/682812
(3) is symmetrical with (5)
00:35:769 (2) - very minor thing but why not make this a blanket?

ofc you would have to move some hit circles a little bit -
http://osu-ppy-sh.jeuxcrack.net/ss/682817
00:59:668 (5) - I would add NC here, because she starts singing the chorus again, so I think you should emphasize it, also, don't keep previous combo just to have symmetry >.<
01:00:176 (6,1) - (1) is a bit weird in my opinion, because in the lyrics she finishes singing a word and not starts it, and also, the end of that slider only fits a beat, but doesn't fit lyrics, I think you could just leave that white tick empty (you did that before this slider anyway), so I think this would work a lot better -
http://puu.sh/2rdvB
It's a pretty nice difficulty.
Insane:
Add lead-in, like in the other difficulties.
00:18:142 (2) - I think this hit circle is kind of unnecessary, because she doesn't really sing at this point, so I would remove this hit circle
00:21:701 (1) - well this does fit the lyrics, but you miss to hit the big beats, not that necessary but maybe you could try to add hit circles or short sliders instead of this long slider
00:24:413 (1,1,1) - if you are trying to make them a blanket, then you should make them nicer

so, don't make such a big curve, example -
http://puu.sh/2re2j
00:26:956 (5) - ctrl+G on this slider for better flow?
00:48:312 - she already starts singing here, and it's also confusing without it, because it feels like the slider starts too late, so I think it would be nice if you added a hit circle
00:58:820 (6) - continue the stream, because it feels like the flow is kind of killed and that space is too empty
01:09:668 (6) - it feels like this is alone, and before and after it's too empty, while there are still beats in the backgroun so you should continue that stream imo

-
http://osu-ppy-sh.jeuxcrack.net/ss/682886 - plus it feels like the flow is killed if you don't add anything >.<
Very nice diff!
Overall very nice mapset, good luck with it!
EDIT: btw, I hope I can get a reply on my mod, so what you changed or didn't, so if you guys have the time to answer, please do so, thanks!
