Hi! Mod4mod :3
Normal:00:03:392 (4) - this feels unnecessary, I can't really hear anything outstanding in the music, which would mean adding a hit circle, and it feels weird to click too, so I think you should remove this hit circle
00:06:820 (4) - same as above ^
00:10:249 (4) - ^
00:13:677 (4) - ^
00:17:106 (4) - ^
00:19:249 (3,4) - these sliders sound weird, I think this kind of mapping would fit better to the melody -
http://puu.sh/3xhHa.jpg - and you can hear, that the melody is here 00:19:534 - and not 00:19:677 -
00:25:249 (2) - the whistle at the end sounds kind of out of place, it is too loud, so I think something softer would fit better
00:56:106 (5) - I think the Normal whistle doesn't sound good here, so try soft one?
01:07:249 (1,2) - I think you could try one of the rythms, so either a repeat slider (which is shorter than the slider you used) or a longer one, because the ones you use don't fit so wel in my opinion -
http://puu.sh/3xmEi.jpg01:20:677 (4) - this note feels quite unnecessary, and it feels weird to play, I think you should remove it, the piano is not as loud as the melody, so that's why it is not so necessary to emphasize the piano
02:02:106 (1,2) - the same as 01:07:249 (1,2) -
02:29:534 (1) - why don't you try placing this a little bit more to the left? it is not so nice like this, because it overlaps, something like this would look better -
http://puu.sh/3xn0K.jpgWell I can see that you try to follow the piano more than the louder melody, but I hope you'll consider some of those kind of suggestions.
Hard:00:18:392 (3) - why don't you try this for better flow? -
http://osu.ppy.sh/ss/854285 - since it leads in the opposite direction
00:26:963 (1) - the whistle sounds too loud, well if you don't want to turn it soft then maybe you could lower the sound of the whistle?
00:30:392 (7) - I think this slider should be longer, because the melody also lasts longer, and you just end it halfway, it should last until 00:30:963 (8) - so you should remove (8), and then rearrange the pattern a bit
00:40:392 - add hit circle? the melody "asks" for it
00:42:677 (4) - similar sugegstion to what I've shown before -
http://osu.ppy.sh/ss/854292 - it might improve flow
00:44:106 (8) - make this slider longer? (like I mentioned before) but it could also work, if you made it last until 00:44:534 -
00:55:249 (1) - remove this? I don't think it's necessary, the previous note already "finishes" this part
00:56:106 (1) - same thing about the whistle
01:06:392 (6,7) - you should make (6) a long slider and remove (7), at that part I hear a longer melody, so you should use a long slider, so that (7) won't sound weird
01:20:963 (1) - why is there a new combo there? feels kind of unnecessary (even though (10) might be a lot), so why not just add a new combo in the middle somewhere?
01:25:249 (4,1) - stack these?
01:26:964 (4,1) - ^...and some other notes too which come later
01:42:392 (3) - this sounds kind of weird, because the melody ends at this point - 01:42:820 - but you end your slider earlier, so I think you should make it a little bit longer
02:14:677 (6) - new combo maybe? so that the combo won't be so long, and there the melody changes a little bit, so it would fit
02:19:249 (1,3) - not really a nice overlap imo, why don't you try something else?
You should also check AiMod, it mentions the audio.
All in all nice mapset, so there is not much to say, good luck!
