Storyboard:01:05:340 - fix this:
http://osu.ppy.sh/ss/12695BG4-2.png is currently not showing up in the storyboard. It's there, but it isn't visibile because it appears beneath BG4-1.png. You need to move the BG4-2 section in the .osb to be under the BG4-1 section so that it will appear on top.
You need to lower the size of light.png and crop out the extra transparent sections. Right now it contains a lot of extra unnecessary transparent pixels.
Also, when BG4-2.png appears in the storyboard, you should make BG4-1.png disappear or completely fade out so that it isn't still being drawn to the screen (and possibly causing lag for slower machines). Same with story5-1.png and story5-2.png.
Some of the BG changes and flashes seem synced to the song oddly. It would look better if these (story1-1, story2-1 and 2-2, story3-1, story4-1 and 4-2, story6-1 and 6-2, story7, and story8) appeared on the large white ticks, like where the 3 is in this screenshot:
http://osu.ppy.sh/ss/12698 You don't have to do that, but it would sync to the song better. Right now they all seem to appear on the white tick right before the large one (like where the 9 is in the screenshot), which doesn't sync up as well. For example, the one at 01:43:888 looks nice because it fades in on the large white beat.
Easy:00:47:114 (2,3) - really confusing for easy
00:49:695 (2,3) - ^
01:07:759 (2) - the end of this slider sounds so weird. remove a repeat, and then possibly put a circle at 01:09:050.
Hard:Makes more sense to begin the first kiai part at 01:20:663 and the second part at 02:27:759 (like in Easy).
，皮肤也很棒！
Put it at 01:09:372 on the red tick
