Wow, nice hitcircle skin, really like it. Difficulty names are also fine for me, I like what you did with them.
Overall for all 3 difficulties: I feel that using 100% volume at the start was a tad loud, perhaps you would be willing to try 90%?
You had some parts with excellent volume control but there are more parts of the song that could use volume control, if you don't mind the trouble you should look through and add those as well to make your map even better.
For storyboarded lyrics, why not use the same font for both English and Romaji? I'm only nazing this because I am a karaoke stylist/typesetter/font designer for a couple fansubbing groups, and we tend to keep these the same and only choose a Japanese font for the Kanji. But anyway all that aside your English translation font was a bit hard to read compared to the Romaji.
Now, particulars.

00:56:78 (1,2,3,4,1) - I like the volume control here, great.
01:09:87 (1,2,3,4,5) - You could add similar volume control here.
01:24:32 (1,2,3,4,5,6,7,8,9,10,11) - Could definitively add volume control here as well, would sound better.

00:38:23 (1,2,3,4,5,6,7,8) - Nice.
00:53:10 (1) - Fade out on this spinner?

Sounds good when Auto plays it but...throws me off terribly. I think you should re-arrange this difficulty if you can.
Just suggestions, keep what you like and change what you like ^_^
