[Skin]*BgCTB.jpg isn't being used anymore, so delete it.
*Bg.jpg is far from a nice 4:3 ratio (such as 1024x768 or 800x600). The black letterboxing at the top and the bottom make it look really strange, so I suggest cropping it or finding a better background.
*comboburst-2.png needs to be horizontally flipped. The right side is cut off.
*The extra shadows around count3.png's feet could have been cropped a bit better (since they're noticeable).
*It's usually preferred to grayscale the hitcircle and the overlay, but I guess it's not a big deal...
*hitcircleoverlay.png is slightly chopped off at the top, but again, not a big deal.
*ready.png is definitely too big. The extra shadows around it look a bit strange and I'm afraid that it might cause some lag. Could you please crop out all of the unnecessary transparency from it?
*You're missing a spinner-approachcircle. Even if it's the default one, add it to complete the spinner set.
*I was concerned about the spinner-circle not having a visible center, but it looks like her hand is actually centered and works quite well as a reference point. owo
[Storyboard]*There is NO reason for your lyrics to be >900px wide. Cropping them to 800px or below would be preferred, but 640px width would be much better (and more optimized).
*You could also crop out the unneeded transparency from the sides of lyrics-8/11/12, but it won't be a problem if you don't (especially after you crop all of the lyrics down to a smaller width).
*Lyrics 12 (no buts) could be centered a bit better. It's noticeably too far to the left.
[General]*"I've" won't work as a tag since apostrophes break search, so use "ive" instead.
*There's no point in having an audio lead-in on Easy/Normal/Hard since they don't start right at the beginning, so remove the lead-in please.
*Source is capitalized/spaced wrong. It should be "To
aru Majutsu
no Index II" It looks like the two ranked maps have "To Aru", but wiki/other sites have it as "Toaru". Hmm... well, at least uncapitalize the "No".
*The other two ranked maps also have the artist in the Japanese form: Kawada Mami. I suggest changing it
by following these instructions to make sure you don't upload a duplicate map.
*Offset could use a +5.
[Easy]00:13:385 (1) - Perhaps add a break after this like in Normal?
00:33:713 (8) - Expected this to end a white tick earlier. (also: same break suggestion)
01:02:402 (2,3) - I recommend making these a slider since they're offbeats
01:12:238 (1,2,3) - I advise against doing a pattern like this in an Easy diff since the level may be confusing.
01:16:008 (1) - Perhaps move this to the next red tick and shorten?
http://puu.sh/Hqb*Overall, this is a bit too fast-paced for my liking (plus you're a bit close to a 3 star rating), but I suppose it's okay.
[Normal]*Perhaps lower Overall Difficulty by one tick?
00:46:828 (5,6) - The overlap makes 6 look more confusing than it is.
http://puu.sh/Hq9 Could you move 4/5/6 around so that 5 isn't on top of 6?
01:10:107 (2,3) - not stacked properly
01:16:336 (1) - Sounds strange. Why not end it on the previous red tick like in Easy?
01:28:795 (1) - Perhaps center this and change the combo to a different color? (The blue blends in with the spinner/background, but can be changed by selecting the slider and hitting the arrow on the new combo icon:
http://puu.sh/Hqi)
[Hard]*Perhaps lower Overall Difficulty by one tick?
00:16:008 (1,2,3,4,1,2,3,4,1,2,3,4) - How about spacing these all out more? Right now it's a big cluster and a bit confusing (and doesn't match the rest of the map).
00:46:172 (1,2,3,4,5) - Try spreading these out a little bit more so that (5) isn't hidden so much. Also, you could new combo 5 to make it even more visible.
00:52:730 - Keep kiai consistent with your other difficulties by starting it here. It seems strange being on the spinner anyway.
01:16:336 (1) - Not sure why you made this so long. It'd look much better ending at 01:18:139 with a clap like in your other diffs.
01:23:549 (6) - I love that you silenced this.
[31's Taiko]01:23:877 - Perhaps end kiai here instead?
[Nekoo's Insane]00:28:467 (7) - How about removing two repeats from this? The last repeating slider like this had 1/2 a beat until the next note, while this one only has 1/4th (which is a bit too short, imo)
01:01:582 (1,2,3,4) - This broke my sightreading. Perhaps unstack 1/2?
