-You have an empty osb file in your folder, delete it
-Include a hit circle approach circle from the template skin in your folder
-Kiai time needs to start and end at the same places on Easy/Normal/Hard
-Looking at your spinner around the center it seems to move around alot, do you intend for this? (otherwise fix)
-Maybe make the spinner approach circle a darker blue so it is easier to see?
-Change "Thank for playing" to "Thanks for playing"
-Your sb load goes over 5 for certain parts of the map (for more than a few seconds) try and lower this if possible
-Combo burst 0 and 1 looks better flipped horizontally in my opinion
-A few of the combo bursts could have some some transparency (look at them carefully) example:
http://osu.ppy.sh/ss/29218Easy:00:57:596 (2) - might not be good for an easy (alot of repeats)
01:13:196 (4,5,1) - align?
01:15:596 (2,3) - might not be good for an easy
01:47:996 (4) - add note?
01:52:796 (3) - ^
01:57:596 (1) - remove new combo
02:10:796 (4,5,1) - make sure spacing stays equal
03:16:196 (3) - could be slightly more symmetrical
03:35:996 (2,4) - align
04:22:196 (1,3) - ^
Normal:00:41:396 (1) - could be slightly more symmetrical
00:41:396 (1,3) - align these two and put 00:43:196 (2) in the middle of them
01:10:196 (2,3,4,5,1) - align both sides of this?
02:01:796 (7,1) - try and avoid anti jumps
03:04:496 (2,3,4,5,6) - make a nicer pattern?
03:22:196 (2) - could be slightly more symmetrical (go though and check all of these..nazi though)
03:42:296 (6,1) - would look better centered on the curve
Hard:Kind of low stats for a Hard (I suggest +1 to HP/OD/AR)
03:30:596 - add break here
03:35:996 (8,1) - stacking is off
Taiko:01:11:096 (181,182,183) - don't have a finish at the end here
Only error I see
Maps are looking nice but I don't think you are quite ready for bubble yet
