Hi. Mods are suggestions only. If you disagree, please explain why instead of just no.
General:
Your NC really bothered me since they were not consistent at all. Maybe add NC every 2 downbeat? (big white tick) I think it's good distance and note density for NCs.
Also you had sliders end on big white tick. I'm not a fan of that (maybe others are! Just my opinion). Since downbeat is a strong beat and you made slider end there which doesn't make it feel as strong as possible. Just something for you to consider if you wanna change some notes/sliders.
Easy:
00:37:254 (1) - Remove NC for consistency with 00:43:607 (3) - ?
00:48:548 (1) - Remove Nc for consistency? Probably won't mention anymore NC since people don't like NC mods orz.
00:54:196 (1) - The long slider here seems very awkward. To me I think the slider is too long and doesn't feel like a good spot for a long slider. Perhaps try this combo instead?
http://puu.sh/3aXWT.jpg01:08:313 (1,2,3,4,5) - Perhaps redesign combo? Because it's very similar to 00:59:843 (1,2,3,4,1). Maybe you could move 01:06:901 (4,5,6) - like this?
http://puu.sh/3aY1u.jpg01:18:196 (1) - I suggest spacing this a little farther. The distance here got changed because you used slow down. I suggest putting like DS 1.2x to move it a little farther so beginners dont click early.
Normal:
The gap from normal to hard seems really big. Perhaps +2 AR and +1 OD? Ar increased cause of slider velocity.
00:12:548 (2,3) - I personally like it more if maybe pattern was like this?http://puu.sh/3aY8M.jpg It sounds much better and starting slider on red tick is usually weird.
00:16:784 (3) - Maybe make this 3 notes instead? The slider end irritates me since it's a strong beat (downbeat) but slider end usually doesn't emphasize it because you don't click it.
00:58:078 (2,3) - Simplify rhythm? Just like at 01:09:372 (2,3) ?
01:01:960 (1) - I really suggest either 1 1/2 slider and then note or 3 notes. I think this downbeat really deserves a note and not slider end. And you can also get rid of ugly NC here. You NC'd the slider but really he sings on same line. When downbeat happens, he sings a different line.
01:22:431 (1) - Forgot finish?
01:33:725 (1,2) - Make 1 a 1/2 slider with repeat instead and 2 a note. Again slider on red tick here but I think having 1 as slider instead feels much better.
Hard:
00:59:490 (1,2,3) - I would say space farther since you made 00:55:254 (2,3,4,5,1,2,3,4) - a jump pattern. Both look same distance apart but timeline is different. I think making 00:59:490 (1,2,3) a jump would keep the flow.
01:11:137 (1,6) - I don't really like this too much. 1,2 are jump 5,6 is correct spacing, but both look similar. Perhaps just make 1,2 same distance?
01:22:431 (2) - NC? You kinda did it for all diffs.
Insane:
01:21:019 (1) - I really liked it if you didn't have spinner here. It seems really nice to just map to it instead imo. I'm not really a fan of spinner end and kiai since you usually have to wait 1/2 or so before you start actually playing during kiai which kinda ruins the start of "epic" in your map. Remove spinner and map here?
01:33:725 (7) - Add finish
