As per your request:
[General]
DC's Easy has a different preview point than the rest of the difficulties. Please line that up.
Please crop the extra transparency from the three "Beatmap by:" images.
A spinnerapproachcircle would be nice.
[DC's Easy]
Maybe HP drain -1?
Eeew, so many whistles on slider slides.
01:47:539 (3,1) - This spacing is kinda deceitful for an easy.
03:19:155 - Sounds better if you completely silence the end of the spinner.
Nice~
[Normal]
00:43:386 (2) - Do an H-flip to reduce overlap
01:14:309 (1,2,3,4,5,6,7,8) - Not a very eye-pleasing pattern. Well, I guess there are a lot with some-what random-looking placement. :/
I like what you did with the start of each chorus, but what you do afterward it kind of dulls the sheen. It goes into a nice slowly spinning circle of vocal happiness to 1/4 1/4 1/4 1/4 1/4 1/4 1/4 *yawn* Think you could spruce up the rhythmic end of this difficulty a bit? As it is, it's all technically fine, but only has small bursts of fun.
[Hard]
00:35:770 (1,2,3,4,5,6,7,8,9,10,11) - I really think this is pushing out of the territory of a Hard difficulty. Think you can work in some consecutive repeating sliders instead? basically applies to any of these streams that are longer than 5 beats, if you choose to do this.
03:19:155 - Just delete that second to last timing section and make this last timing section the end of the kiai time. Also I would like to suggest you reduce the volume to minimum.
Kinda wish you followed the lyrics a little more than you do. :< Otherwise fine though.
[Roddie's Hard]
00:52:616 (2,3) - It might be asking for a lot, but do you think when you use stacked sliders like this you could try to make them look like one smooth curve instead of humped like they are now?
01:41:539 (9) - Hrm... it'd be neat if you could line up the slider end with the 8.
03:19:155 - Sounds better if you completely silence the end of the slider.
Normal felt a little boring to me, but the other diffs were nice~
