first of all i can say that those are nowhere near insane difficulties. armins insane is a hard with small CS. the only pattern thats more challenging is 00:25:604 (1,2,3,4,5,6,7,8) - in the highest difficulty. you need to rethink armins level name. the way its mapped is a hard but the CS makes it more like hard+ but nothing more. 5 CS would be more appropriate for how its mapped. the SVs are also very slow in all diffs which makes them even more easy. but yes, apart from a few jumps on the hardest diffs, they look like Hards to me. the hardest diff in a set can have individual naming but you need to think armins level through again so it fits the set and represents its actual mapping.
you also need to think of some tags to add in addition to armins missing tag that you need to add as well since he is part of the set.
phantasm00:33:952 (1,2,3,4) - would be smoother with spacing like 00:23:517 (1,2,3,4,5,6,7,8) -
hard00:33:952 (1,2,3,4) - same like phantasm
these parts are really repetitive 00:02:648 (1,2,3,1,2,3,1,2,3,1,2,3,1,2,3,1,2,3) - try to replace some of them with rhythms like

normal00:15:169 (1,2) - 00:48:561 (1,2) - i dont necessarily disagree with multiple reversed sliders in a normal but these are really short and hard to read for new players since the slider ball circle stays in the same spot which means the cursor doesnt move and thus makes this not readable. you either can remove a reverse on each
http://puu.sh/sV4tT/cdadc3d704.jpg or find something different but i strongly recommend that you dont use such short multiple reverse sliders in easier diffs-
00:29:778 (1) - little hard to read and might get confusing for new players since the ending point is half covered. space the slider point out a bit more
http://puu.sh/sV4z5/51551e3e2a.jpg00:34:995 (1) - same as easy, dont use sv changes in lower diffs for short sliders or more any at all. easy - normal should really only teach basics. drastic sv changes, spacing changes are not suited for these levels.
easy00:06:821 (1,2) - definitely could blanket these better
00:16:213 (2,3,1) - 00:48:561 (1,2,3,1) - you should never change the spacing in an easy. use 0,8 like the rest of it. you can change sv and ds slightly for sections of a song like the kiai which is more intense, but not for such short time.
00:18:300 (1) -00:34:995 (1) - nor should you ever use such shorthanded sv decreases in easies, remove this as well. its very confusin for beginners. even more since visually 00:17:256 (3,1) - those have the same length. not even the NC indicator will help noticing the change. these should be introduced in hard+ but never below.
easy also ends half a beat too early. all the other diffs end at the same spot except easy so extend the slider for consistency.
overall smooth except what i pointed out. other than really nice mapset
