[Normal]Consider raising OD and HP drain by +1 each. It doesn't change very much but feels more in line with your intentional difficulty setting for this map.
I don't have any problems with this set only having 2 difficulties. This [Normal] however is mostly an "Easy" with a few normal difficulty parts in it. You could add some more details here and there (1/2 notes) to spice it up
a bit. 2.50 stars leaves some space for the normal criteria. This way you could avoid ppl telling you to map a "N" to even the difficulty spread of E-I a bit. As this map is already polished I will focus on those details in my suggestions. Feel free to ignore them
after you tried some of them.
01:02:589 (4) - I was expecting another 1/2 slider here like before @00:58:868 (4) -
01:10:031 (4) - Starting the new phrase on the vocals can be done and it works - but I wouldn't recommend it here. Feels much more natural to actually map the downbeat on 01:10:496 - as beginners will probably hit 01:10:728 (1) - very early if they don't know the song itself. You can try to add a repeat on (4) and rearrange the pattern a bit.
01:13:752 (4) - ^same as above, danger of hitting 01:14:449 (1) - early.
01:36:542 (2) - maybe split this and start the slider on the downbeat, mapping the original starting point as a circle to add a little more action that goes with the vocals (and you can add the whistle on 01:37:007 to support your established pattern):
http://osu.ppy.sh/ss/470021 [Hard]You tend to slide over many pronounced downbeats. This is not a huge problem in this case as you follow mostly vocals or a mix of beat and vocals and most of the ignored downbeats can be explained with that. But some of those downbeats actually impacted gameplay for me so I will point them out.
00:27:474 (3) - add whistle to make it consistent with patterns before and after this combo
01:03:054 (1) - "ahhhahahhh"
01:08:635 (1) - maybe remove whistle from beginning, doesn't really fit here song wise and doesn't fit your established pattern
01:32:589 (1,2) - Choice of hitobjects feels a bit off here. Beat placement itself is great but the input required from the player seems a bit unintuitive. You could try to map this triplet properly and start a slider on the downbeat instead of ending the repeating slider there:
http://osu.ppy.sh/ss/469975 this is purely a suggestion to improve the "feeling" of the map. The little kick slider isn't really adding to the flow of the vocals here imo.
01:40:495 (1) - Another downbeat left out that feels weird. I highly recommend mapping this downbeat in any way. Even a turning point of a repeating slider would be enough here:
http://osu.ppy.sh/ss/46996901:38:402 (4) - why isn't this stacked properly? The custom stack has the exact same distance as the automatic one. If you want to use a custom stack you should do something the automatic one wouldn't do...like stacking exactly vertical:
http://osu.ppy.sh/ss/469942 but that doesn't really look any better here. So if you don't intend to do something special with the custom stack you shouldn't use it in the first place.
02:07:472 (2) - missed a clap on the ending point here? You used claps here in the parts before. Better add the claps for this part as well for the sake of consistency.
02:09:798 (3) - missed a clap?
02:11:658 (3) - ^
02:15:379 (3) - missed clap on the beginning?
02:51:192 (5,6) - same as 01:32:589 (1,2)
02:33:286 (1,1,1) - I love this effect with the SB!
Great (even if a bit thin) mapset! I'll say that renaming [Normal] to [Easy] and mapping a ~3.5 star "Normal" would benefit the difficulty spread. It would also avoid complaints on the way to getting this ranked. But on the other hand I don't see how to achieve this while making the new diff in the middle different enough from both the other diffs. Therefore I think this is one of the rare instances a 2-map-set feels "complete". Have this~
I'll be back soon...
