A thousand apologies for taking so long to get back to this.
[General]*comboburst.wav: 1.09MB? That's just ridiculous for a sound file...
*failsound.wav: 1.27MB?
*If you're going to include ctb skin elements, then also add a fruit-drop to complete the set (even if it's just the default one).
*You have a non-empty .osb that refers to images that don't exist, so just remove that.
*I love the authentic guitar-hero hitcircles, but I'm a bit concerned with the lack of numbers...
[Easy]*I suggeast lowering OD/Drain one tick each. 3 seems a bit high for Easy, and Normal is already using 3 for those.
00:57:186 (1) - This note even threw me off... How about making 00:57:186 (1,2) a slider to avoid having a red-tick note by itself?
01:03:837 (2,3) - Expected this to be a single repeating slider like 01:00:629 (3).
01:11:739 (1) - Again, a bit unexpected. Changing 01:11:739 (1,2) to a slider or something similar should flow much better.
01:56:125 (1) - The rhythm should be a bit more intuitive by now, but I still think a slider would make more sense.
02:04:640 - Expected a note here
02:05:100 (1) - Perhaps finish the end of this?
02:07:364 (2) - Sounds awkward since "and the rain" starts 1/2 before. Maybe try something like....
http://puu.sh/1Vzb03:19:541 (1) - Expected this to start on the previous red tick. Also, perhaps try something like
http://puu.sh/1VzU instead to make things flow better?
*Overall, I think that this diff makes a nice "Easy", but it still feels a bit too fast-paced... The slider velocity is the same as Normal's, and the distance spacing is a bit larger than I would expect for an Easy. Without having to remap, I think that the best solution to avoid this feeling so fast-paced would be to lower the tick rate. It doesn't need to be the same on every difficulty, and 2 just sounds too noisy/fast for an Easy.
[Normal]01:55:897 - The sampleset change in the middle of the slider sounds odd. Try moving the inherited section to the end of the slider instead.
03:16:370 (1,2,3,1,2,3) - I highly suggest changing these into repeating sliders. The pattern/rhythm is just too unpredictable for a Normal.
*Again, this diff felt a bit more difficult than I expected, but there's really nothing "odd" for me to point out that I haven't already.
[Rolled's Hard]*Some notes are unsnapped; check AIMod.
02:05:100 (1) - Perhaps colorhax this to yellow to match "thunder"? Even though there's no sliderart, it would stay consistent with the other diffs. Plus, then 02:07:137 (1) would be blue for "rain".
03:16:370 (1) - Might wanna silence those slider ticks.
[Expert]02:18:652 (1) - oh my god YESSSS
02:38:297 (1) - Perhaps move to the white tick and shorten?
03:01:633 (1) - I know that it fits, but it's the only single 1/4 note in the difficulty; which just isn't intuitive...
03:12:670 (1,2,3) - Doesn't flow well at all... How about something like
http://puu.sh/1VBF instead?
I'm a bit disappointed that the full song wasn't mapped, as this would have made an amazing approval map. :c Oh well, it's still awesome! Also, I'm still working on the timing, so I'll post that as soon as possible.
